SCOM R2: CU3 Agent Install Issue and Fix – Error 80070641
So I had to roll CU3 to production today and one of my agents was throwing an odd error:
The Agent Management Operation Agent Install failed for remote computer servername.domain.com.
Install account: myaccount
Error Code: 80070641
Error Description: The Windows Installer Service could not be accessed. This can occur if you are running Windows in safe mode, or if the Windows Installer is not correctly installed. Contact your support personnel for assistance.
Microsoft Installer Error Description:
For more information, see Windows Installer log file “(null)” on the Management Server.
I thought this was odd and had never seen it before. Did a little “google” search for this issue and found this KB that mentioned the windows installer service could be unregistered or corrupt. After I followed the steps in the article, I tried to install the update to the agent and it was successful. Very nice!
