We had an application that was running on window xp. The app is a desktop .net application which runs on the pc/laptop, all local. The app wrote to c:\programdata. Some customers upgraded the pc's to windows 7 and windows 10. Regular users can not access the files anymore, they have to have user administrator accounts to use the app.
I have tried to change the permissions programmatically which works only if you are an administrator running the program. Basic users get the "need to be admin or no rights" error.
I can only have one instance of the application on a pc as the users need to share the same database and files.
Has anyone been able to fix this so users can access c:\programdata?
