But the modules are being uninstalled, not deactivated. Yes, they need to be activated again once installed, but if a module just loses activation, it won’t get uninstalled.
When you install a module, the module DLL is copied to
C:\Users\<user>\Documents\SambaPOS5\Addons. I would be inclined to see if there is some permissions issue on your My Documents folder. Also when they are uninstalled, do they still exist in the
Addons folder? If yes, likely a permission issue, if not, something/someone is deleting them.
I wonder did you recently get the April 2018 updated on Windows 10? I just received it and there is a whole load of new privacy questions (mostly related to GDPR I am sure), but I also noticed some software I use like Google Sync required my login again after the update, so obviously “something” changed, not sure if that is related or not.
