Set-AppDirPermissions

14 April 2018

Description:

Function can be used in application package/adjustments/shimming scripts to set directory permissions for applications that run as the user which require non-standard modify access to non-user profile (appdata) specific paths. Disclaimer here: You only want to do this if you absolutely have to! In an ideal world, this wouldn't be necessary at all, however, there are many vendors today who still release applications which run as the user but write to Program Files or ProgramData instead of the User's AppData directory. In these cases, it is better to make the adjustment to that directory to allow write access than to give users local admin rights!

Language:

Powershell
