Silent uninstall problem

[shetty_rohan]

Hi,

I have written a setup(using the latest AdvancecInstaller), in which I use the following command for the silent uninstall
msiexec.exe /qn /uninstall {2631383F-852E-4BEA-8126-FF838E8D769F} /l*v installqn.log
which works fine in most of the operating systems.

However, in Windows 8.1, it does not seem to be working.

Testcase 1:
On windows 8.1, I ran the uninstall in UI mode using the following command
msiexec.exe /uninstall {2631383F-852E-4BEA-8126-FF838E8D769F} /l*v install.log
which is working fine

Testcase 2:
On windows 8.1, I ran the uninstall in silent mode using the following command
msiexec.exe /qn /uninstall {2631383F-852E-4BEA-8126-FF838E8D769F} /l*v installqn.log
which is NOT working fine.

Please find attached the logs for the same.

Note: If you need the aip file, do let me know. Since it is huge, I have not sent it to you.

Hi Rohan,

Looking over your log file created with the "/qn" parameter, I noticed the following message: You must be an Administrator to remove this application. To remove this application, you can log on as an Administrator, or contact your technical support group for assistance.

So, please make sure that you try to uninstall the application from an administrator account and also launch the command prompt using the "Run as administrator" option.

I also tested this scenario on a Windows 8.1 machine and it worked well to me.

Best regards,

Thanks for the quick response

I have been using a user which belongs to "Administrators" group. I have used the same account for the "UI mode" installation, which is working fine.

When I tried with /qr, I get the following window

So ,is this happening because of the "User Account Control"?

Hi Rohan,

Yes, when the application is uninstalled in silent mode, the UAC is not displayed, but the uninstallation fails because the application does not have the necessary permissions.

In order to give administrator rights to the application, you should launch the uninstallation from an elevated console (a console that is launch using the "Run as administrator" option).
