Windows Installer Error: "The system administrator has configured your system policy to prohibit this installation."

Question

Windows Installer Error: "The system administrator has configured your system policy to prohibit this installation."

Michaël PAUL 0

Hello everyone,

I am faced with a problem whose origin I do not understand and I hope that the community will enlighten me or guide me to resolve it.

I am on a Windows Server 2019 Standard virtual machine - Version: 1809 - OS Build: 17763.4974.

The server is installed as standard and updated to be delivered to the application team without any modified local security policy.


My concern is that each user (administrator) must be able to install the MSI "PulseSecureAppLauncher".

The initial administrator account poses no problem but all other local administrator accounts have the following problem:

Windows Installer Error: "The system administrator has configured your system policy to prohibit this installation."

The Windows Installer service is successfully started.

Have you ever encountered this problem? Do you have any leads?

Thank you very much in advance.

Sincerely.

Mr. PAUL.

Answer 1

Hi,

Is this virtual machine a domain computer? If yes, run gpresult /R to display the applied group policies and see if any of them configures "Turn off Windows Installer". Also make sure the registry value
HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Installer\DisableMSI does not exist.

Hi,

Thank you for your reply.

In the registry, there is no key mentioned.

The server is a standalone server and not in a domain.

Here is still the result of gpresult /R

PS C:\Windows\system32> gpresult /R
