Valid Environment Variables for Controlling Licensing Behavior

Name	Possible Settings
`ALM_HHWU`	Controls where the application will search for licenses. Unset, the application will try On-Premises server then Altair Units (if the machine is authorized). Set to “T” will only use Altair Units. Set to “F” will only use On-Premises Server.
`ALM_HHWU_CONFIG`	Overrides the default directory for storing the Altair Units config file.
`ALM_HHWU_USE_WININET` (Windows Only)	The default proxy information (if required) is stored in the Altair Units config file. Setting this variable to “T” allows the applications to use the Windows Global proxy settings and supports interactive password prompts, and so on. Recommended only for GUI applications. Batch (solvers) should not have this set in their environments.
`ALTAIR_LICENSE_PATH`	Set to point to On-Premises license server or NodeLocked license. Do not set if you only want to use Altair Units.
