CU8 Update Fails with Error

Hi, we're trying to update our Exchange Server 2013 from CU7 to CU8.  One of our servers updated successfully (with problems after installing but were resolved).  One our production server, when running the update we receive an error saying the following:

"Incomplete Installation Detected" followed by "Setup has detected that a previous installation of exchange on this computer didn't complete successfully.  Setup will try to complete this installation.  Click next to continue."

When we click on next, the setup fails with an error saying the following:

"Warning: An unexpected error has occurred and a Watson dump is being generated:  Could not find a part of the path 'C:\Windows\Temp\ExchangeSetup\bin\EnterpriseServiceEndpointsConfig.xml'."

We found a path like that in a different directory and copied it so it matched the path and file but when running the setup again, the file got deleted and we received the same error.  Also couldn't find a .dmp file or log file in the Windows debug folder that had to do with this error.

Any help would be appreciated.

Thanks,

John

Hello,

This seems to be an abnormal behavior. I suggest we temporarily close any third-party antivirus programs and then try the updating again.

Thanks,
