How do I apply a SETINIT license key to Altair SLC on a Windows-based platform?
Altair EmployeeThese steps can be followed to apply a new setinit license for the first time, or to replace an existing license that has expired or that needs to be superseded.
Please note that the legacy "setinit" (wpskey) license method has been phased out in favour of the Altair Units license method. Please refer elsewhere to information on how to apply Altair Units licenses to your SLC software.
Instructions for SLC 2023 and later versions
A legacy license key can be applied either in the workbench GUI using Help->Apply License or using the command line interface in a CMD command prompt window of the form:
"C:\Program Files\Altair\slc\2023\bin\wps.exe" -stdio -setinit < license.wpskey
The compiled key is typically stored at
C:\ProgramData\Altair\slc\5\setinit.dat
If you get "Access is denied" errors (e.g. "You do not have the relevant write permissions to apply a license to this computer") then it is possible someone else on that Windows operating system created the initial license. Please rename or remove this setinit.dat file and re-apply the license key.
Instructions for WPS / SLC 4.x versions
A license key can be applied either in the workbench GUI using Help->Apply License or using the command line interface in a CMD command prompt window of the form:
"C:\Program Files\World Programming\WPS\4\bin\wps.exe" -stdio -setinit < license.wpskey
The compiled key is typically stored at
C:\ProgramData\World Programming\WPS\4\setinit.dat
If you get "Access is denied" errors (e.g. "You do not have the relevant write permissions to apply a license to this computer") then it is possible someone else on that Windows operating system created the initial license. Please rename or remove this setinit.dat file and re-apply the license key.
