I tried the purge batch file from <https://forums.stardock.com/488142/groupy-support-faq#reinstalling>
It says this
The Stardock Groupy service is not started.
More help is available by typing NET HELPMSG 3521.
C:\WINDOWS\system32>net helpmsg 3521
The *** service is not started.
**How is that more help?**
I've uninstalled and reinstalled. Works fine on my home desktop. Doesn't run on corp laptop.
