MSI: The System Administrator has set policies to prevent this installation

Hi everyone

Today I wanted to talk a problem I seen on newer Windows Server 2019 in a RD setup.

Some user were having problem with a GPO for software installation (per user).

After some diagnostic I found on all my 2019 that the MSI system is restircted now by default.

If you stumble upon this bug;

enter image description here

Then you must be like me, and you have a registry to change.

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer]
“DisableMSI”=dword:00000000

Now it should work.
