So in my case... the extracted files from the update do not allow installing via an MSI. I tried... did not succeed... Just the standard files are installed, no updates... I still want to use the MSI, because it is so easy to put a computer in a security group (with GPO) and the application is installed and uninstalled when I remove the SG. If I use the setup, it will run in User context I guess? So a normal user does not have the proper rights... And... When it is installed... It can't be removed by simply removing the GPO from the computer? Regards Rob
