Is this definitely what you want- e.g. is it certain that no customer ever will want data on a server for automated backups etc? Perhaps you could default to a folder in %public% while allowing/encouraging advanced users to overwrite with their preferred server/folder.

Well, this document suggests that ProgramData/AppName folder is fine and setting its permissions is fine also (that's what our installers are doing)

The problem seems to be localized to the latest build, so we need to figure out what exactly went wrong with it.
