How Do I Perform A Silent Installation Of ESRD Software Products?

Windows does support a silent installation option for all .msi files. Msiexec is the program that “interprets packages and installs products” (see links below) and can be run from the command line. Please note that any command line installation must occur from a command line being run as an administrator.

To run command line as administrator: Click on the start menu. In the search box, type cmd. Wait while Windows searches. In the list of found programs, right click on cmd (or cmd.exe) and choose “Run as administrator.”

Some condensed notes about installation options:

To specify the .msi package to be installed, use: /i [path to the .msi file]
To specify the silent installation option, use: /q
- Note that using a completely silent option will not provide any feedback about the success, failure, or completion of the installer. To determine that the process has completed, it is possible to look in the Windows Task Manager Processes tab and watch “msiexec.exe” in the process list. When msiexec disappears from the list, the installer has finished; however, success or failure of a silent installation will not be reported. Alternatively, several other “quiet” options are available. For example, to specify no feedback should occur until the installation ends, at which time a modal dialog box should appear to report the status, use: /qn+

To specify a property value, use the syntax: PROPERTY=VALUE
- For StressCheck^® 10.1 and higher, the property INSTALLLEVEL can be set to 5 to indicate all features should be installed (a “Complete” installation). If INSTALLLEVEL is not specified, StressCheck^® will default to a “Typical” installation.

The following example, when executed from an administrative command line, will perform a silent installation of all features (“Complete” option in the GUI) in the StressCheck^® 10.1 installation package located on user Kristen’s desktop:

msiexec /i “C:\Users\Kristen\Desktop\StressCheck^®PE_10.1_x64.msi” /q INSTALLLEVEL=5

How Do I Install ESRD Software Licenses On An Existing FLEXnet License Server?

Open in a new window

If a FLEXnet 11 License Manager is already serving floating (concurrent) licenses for other software products, or the version of FLEXnet v11 available on the ESRD Resource Library is not the preferred version of FLEXnet, support for ESRD software product licensing is confirmed through FlexNet Publisher 11.16.2.1 build 245043 (64-bit). Follow the below steps to get started with setting up an existing FLEXnet License Manager for concurrent (floating) license management of ESRD software products.

Installing ESRD’s Software Product Vendor Daemons

Download the FLEXnet 11 License Manager package from the ESRD Resource Library. This is required to obtain the ESRD vendor daemons necessary to serve ESRD software product licenses.
Unzip the package, and navigate to the \FLEXnet_11\FLEXnet\program files\FLEXnet folder.
Copy the esrd.exe and esrd2.exe vendor daemons from this folder and paste to the existing FLEXnet 11 License Manager installation folder containing lmgrd.exe (e.g. C:\Program Files (x86)\FLEXnet).
After the copy/paste operation, run the FLEX LMtools utility (lmtools.exe) from your existing installation of FLEXnet 11.

Note: This operation requires administrative privileges. If you have already sent your FLEXnet server’s HOST ID to ESRD Support, you may skip steps to obtain the server HOST ID.

Updating the Existing FLEXnet License Service for ESRD Software Products

Follow Tip #2 in our Installation and Licensing page to obtain the FLEXnet server’s HOST ID and send to ESRD Support.
If applicable, save a backup copy of your current FLEXnet license file that is serving other applications and then append the content of the new license file sent to you from your ESRD Support representative to the end of your current license file.
- Are no other software products running on your existing installation of FLEXnet 11? Jump down to the “Setting Up a New FLEXnet License Service for ESRD Software Products” section and continue those steps instead of the below.
Remove the “SERVER” lines from the newly copied information so that you do not have these duplicated within the license file, leaving the original “SERVER” lines at the top of the resulting license file.
Move the “VENDOR esrd” and “VENDOR esrd2” lines from the copied information under the “SERVER” lines.
The resulting license file should be in a format similar to the following lines:

SERVER 12345abcdef 111222333444 28518
VENDOR esrd
VENDOR esrd2
#Existing features
FEATURE OTHERSOFTWARE companyvendordaemon …
#ESRD software product features
FEATURE SC_WIN_SC_Ref3D esrd2 …

Note: it may be required to update the port number on the SERVER line. By default, ESRD produces license files which use port 29731 but it may be necessary to use a different port (e.g. 28518).

If not already running, run the FLEX LMtools utility (lmtools.exe), and go to the “Start/Stop/Reread” tab.
DO NOT stop the license server, as this may interrupt licensing for other software products. Click “ReRead License File”.
Verify that the ESRD software licenses are available by selecting the Server Status tab and selecting the “Perform Status Enquiry” button. The status report should display the same license keys that are contained in the license file including those for the ESRD software that you just appended.

Distribution of ESRD Software Product Licenses and Features

Place a copy of the license file named “license.dat” (unedited and including the “SERVER” line(s)) onto each client machine that you have installed the ESRD software. How can I limit usage of certain features?

Note: if the system administrator prefers to have the client provide a port number and server name, instead of using a copy of the license.dat, this is also supported by setting the environment variable ESRD2_LICENSE_FILE.

Verify that the licensed ESRD software product(s) can be run from a client machine on the local network by specifying the license file or server upon startup. Are there issues running the software?

How Do I Install A New FLEXnet License Server Dedicated To Providing ESRD Software Licensing?

Open in a new window

ESRD uses Flexera’s FLEXnet v11 License Manager to manage client requests for ESRD software product features via a local network license server. Follow the below steps to get started with setting up a new FLEXnet License Manager for concurrent (floating) license management of ESRD software products.

Installing ESRD’s FLEXnet v11 License Manager

Download the FLEXnet 11 License Manager package from the ESRD Resource Library. Is another version of FLEXnet already installed and running on the license server?
Unzip the package, and navigate to the \FLEXnet_11\FLEXnet folder. Right-click on setup.exe, and click “Run as administrator”.

Note: you must have Administrative privileges in order to properly install FLEXnet.

Follow the instructions to install FLEXnet 11 on your server machine.

Note: if you have already sent your FLEXnet server’s HOST ID to ESRD Support, you may skip steps to obtain the server HOST ID.

After installation, run the Flexera LMtools utility (lmtools.exe) from the \FLEXnet_11\FLEXnet\program files\FLEXnet folder:

Flexera’s LMTools Utility.

Note: FLEXnet v11.5 is a legacy version of Flexera license management software, and recent Windows Server operating systems may prevent the LMTools.exe included in FLEXnet v11.5 from launching directly (e.g. via double-click of LMTools.exe or running LMTools.exe from the Start menu). In this case, launching LMTools.exe must be performed via command line by right-clicking cmd.exe and selecting “Run as administrator”, navigating to the FLEXnet installation folder containing LMTools.exe (e.g. “cd C:\Program Files (x86)\FLEXnet”) and running “lmtools.exe” by command line.

Setting Up a New FLEXnet License Service for ESRD Software Products

Follow Tip #2 in our Installation and Licensing page to obtain the FLEXnet server’s HOST ID and send to ESRD Support.
When you receive your floating license file from ESRD Support, copy it to the FLEXnet folder and rename it “license.dat”. Make certain that the true file extension is not hidden from view by Windows Explorer.
Run LMtools and select the Configuration using Services bubble in the Service/License File tab.
Select the Start/Stop/Reread tab and click Stop Server.
Select the Config Services tab. If the paths shown for “lmgrd.exe”, “License File”, and “Debug Log File” are not correct, use the corresponding “Browse” buttons to correct each path as necessary.
Activate the switches for “Use Services” and “Start Server at Power-Up”. Click Save Service.
Select the Start/Stop/Reread tab and select Start Server.
Verify that the ESRD product software license FEATURES are available by selecting the Server Status tab and selecting the “Perform Status Enquiry” button.
The FLEXnet license server is configured and running. You should be able to access this license server and run the licensed ESRD software product(s) on any computer within your company local area network. Exit LMTools.

Distribution of ESRD Software Product Licenses and Features

Place a copy of the license file named “license.dat” (unedited and including the “SERVER” line(s)) onto each client machine that you have installed the ESRD software. How can I limit usage of certain features?

Note: if the system administrator prefers to have the client provide a port number and server name, instead of using a copy of the license.dat, this is also supported by setting the environment variable ESRD2_LICENSE_FILE.

Verify that the licensed ESRD software product(s) can be run from a client machine on the local network by specifying the license file or server upon startup. Are there issues running the software?

How Do I Control Which Users Can Access License Features?

Open in a new window

The FLEXnet administrator can control access and permissions of specific FLEXnet licensing features based on user, node or group. This is performed by creating a FLEXnet Options file (.opt) and placing this file in the root directory of your FLEXnet installation.

From Chapter 11, “Managing the Options File” in the FLEXnet v11.5 License Administration Guide:

For concurrent (floating) licenses, the license administrator can:

Allow the use of features

Deny the use of features

Reserve licenses

The concurrent licenses can be held either in license files or in fulfillment records within trusted storage.

For activatable licenses, the license administrator can:

Allow activation of licenses in a specific fulfillment record

Deny activation of licenses in a specific fulfillment record

For all licenses, the license administrator can:

Restrict the number of licenses available

Control the amount of information logged about license usage

Enable a report log file

Options files allow you, as the license administrator, to be as secure or open with licenses as you like. Lines in the options file are limited to 2048 characters. The \ character is a continuation character in options file lines.

Creating an Options File

Use the appropriate options listed in Options File Syntax to create the options file for a vendor daemon using any text editor.
Locate the options file anywhere; however, it is recommended that the options file be placed in the same directory as the license file.
Add the path to the options file in the license file as the fourth field on the VENDOR line for the application’s vendor daemon.
1. For example: VENDOR sampled /etc/sampled \[options=]/sample_app/sampled/licenses/sampled.opt enables the sampled vendor daemon to look at the specified options file.

If the path is omitted, the vendor daemon automatically looks for a file according to the following criteria:

the name of the file is vendor.opt, where vendor is the vendor daemon name
the directory that contains the license file used by lmgrd

The above means that if the name of the vendor daemon (i.e. esrd2.exe) is the same as the options file (esrd2.opt), there is no need to add the path to the options file in the license file. It will be found automatically.

Options File Syntax Examples

EXCLUDE – Deny a user access to a feature.
1. Usage: EXCLUDE feature[:keyword=value] type {name | group_name}
2. Excludes a user or predefined group of users from the list of who is allowed to use the feature.
3. EXCLUDE supersedes INCLUDE; conflicts between the EXCLUDE list and the INCLUDE list are resolved by the EXCLUDE taking precedence.
4. To exclude the user hank from the list of users able to use feature f1:
  1. EXCLUDE f1 USER hank
GROUP – Define a group of users for use with any options.
1. Usage: GROUP group_name user_list
2. Defines a group of users for use in INCLUDE, INCLUDEALL, INCLUDE_ENTITLEMENT, EXCLUDE, EXCLUDEALL, EXCLUDE_ENTITLEMENT, and RESERVE option lines.
3. Multiple GROUP lines for the same group name add all the specified users into the group. To define the group Hackers consisting of bob, howard, and james:
  1. GROUP Hackers bob howard james
4. To specify a list of users or hosts, first define the list using the GROUP or HOST_GROUP option lines,
  then use the GROUP or HOST_GROUP type to specify the group name. For example:
  1. GROUP stars joe barbara susan
  2. EXCLUDE coolsoft GROUP stars
INCLUDE – Allow a user to use a feature.
1. Usage: INCLUDE feature[:keyword=value] type {name | group_name}
2. Includes a user or predefined group of users in the list of who is allowed to use licenses for this feature.
3. Anyone not in an INCLUDE statement is not allowed to use that feature. EXCLUDE supersedes INCLUDE; conflicts between the EXCLUDE list and the INCLUDE list are resolved by the EXCLUDE taking precedence.
4. To include user bob in the list of users able to use feature f1:
  1. INCLUDE f1 USER bob
RESERVE – Reserves licenses for a user or group of users/hosts.
1. Usage: RESERVE num_lic feature[:keyword=value] type {name | group_name}
2. To reserve one license of feature f1 for user mel:
  1. RESERVE 1 f1 USER mel
3. If you want to reserve a license for each of several users or groups, you must use a separate RESERVE
  line for each user or group. If a package name is specified, all components that comprise the package are
  reserved.

Simple Options File Example (Sampled.opt)

GROUP ESRDEngs matt eric andrew
GROUP ESRDDevs kristen dave meng
RESERVE 2 SC10_WIN_SC_Ref3D GROUP ESRDEngs
RESERVE 1 SC10_WIN_SC_Ref3D GROUP ESRDDevs
EXCLUDE SC10_WIN_SC_Ref3D USER lori
NOLOG QUEUED

This options file restricts the use of concurrent licenses as follows:

Defines a group called ESRDEngs and lists users matt, eric and andrew.
Defines a group called ESRDDevs and lists users kristen, dave and meng.
Reserves two licenses for the feature SC10_WIN_SC_Ref3D for the group ESRDEngs.
Reserves one license for the feature SC10_WIN_SC_Ref3D for the group ESRDDevs.
Prevents the user lori from using the SC10_WIN_SC_Ref3D feature on any system on the network.
Causes QUEUED messages to be omitted from the debug log file.

The sum total of the licenses reserved must be less than or equal to the number of licenses specified in the FEATURE line. In the example above, there must be a minimum of three licenses on the SC10_WIN_SC_Ref3D FEATURE line. If fewer licenses are available, only the first set of reservations (up to the license limit) is used.
