I have had a Demo Licence for Altair SLC, but how do I revert to a Personal Edition licence?

I amended the 3rd item in my action list, and now I have a working Analytics Workbench with SLC. Previously only the SLC extension for VScode worked with Altair SLC:

3. Go to C:\Users\[user-profile]\AppData\Local\.altair_licensing and C:\ProgramData\altair and move the CFG files to a safe place elsewhere. Also move the setinit.* files from C:\ProgramData\altair\slc\5 to a safe place. They can be reused later.

However, I have also installed SLC and Analytics Workbench 2027_ea1, which may also have affected my environment.

I have tried the following:

Uninstall Altair SLC and Analytics Workbench, if they are still installed.
Open your Windows registry and go to HKEY_LOCAL_MACHINE > SOFTWARE > Altair, then delete the sub‑folders SLC and Analytics Workbench, if they exist.
Go to C:\Users\[user-profile]\AppData\Local\.altair_licensing and move the CFG files to a safe place elsewhere. They can be reused later.
At the command line type SET ALM_HHWU=FALSE, and make sure ALM_HHWU is not included in the environment variables on startup.
Reinstall Altair SLC and Analytics Workbench using the downloaded software files:
Run the following command on the Command Prompt on Windows:
"C:\Program Files\Altair\SLC\2025\bin\wps.exe" -personal
or run the following command in the Altair SLC desktop icon on Windows:
wps -personal

This is the error message received in Analytics Workbench.

Hi Phil,

I think this situation was caused by:

Computer was still connected to AltairOne where you had an expired license.

By disconnecting (logging out) of AltairOne, the SLC software was then able to discover its own personal license.
