I'm not sure what you set up differently on your two workstations, but I heard about a similar problem. It might be caused that the relative paths in the .bat files are not working on your first workstation for some reason. You can try to edit the .bat files and set an absolute path.
For example open this file in a text editor:
C:\Prism\Win_Setup_Integrations.bat
And change:
start Python37/pythonw.exe Scripts/PrismInstaller.py
to
start C:/Prism/Python37/pythonw.exe C:/Prism/Scripts/PrismInstaller.py
Then save the file and doubleclick it. Don't run it as admin.
