I've been using the following in a .bat file which is run with Install Creator Pro with admin privileges:
cacls %1 /e /g Users:f
It's set for ProgramData\My Folder. The thing is, I don't think it's actually working all the time. Is there a different way I should be doing this? It's essential the files in that folder have full permission because I store the product registration in that location (created after installation, by my program with non-admin rights) and all users on the machine need to access it.
