TM1 Forum

Hi

I am trying to uninstall 9.4 but i getting the following error.

Error 1921. Service () could not be stopped. Verify that you have sufficient privileges to stop system services.

I know that i have seen this before but i cant remember how to fix it. I have full admin rights.
No tm1 service is running including the admin service, and i dont have any other apps open.
Have restarted as well but it gives the same error.

Any advice would be appreciated.

are both the service and the admin server stopped, definately? If so, try manually removing the services from windows before running the uninstaller, i think the details for that are in the "useful code" section.

What has happened is that your registry entries for TM1 have become corrupted during the uninstall.

Open a Service Request with Cognos and they'll send you a .reg file that will clean the dodgy entries out.

Thanks, i managed to edit the registry and got it off. Have installed 9.1 again and everything seems fine now.
