Exchange 2010 Troubleshooting: Rollup Upgrade Fails

  • Article

In any org, not all upgrades succeed, you might come across a server, whether it is a multi-role, CAS, HUB or MBX server where it fails.

The error is a bit cryptic, the setup creates the assemblies and then rolls back immediately with a premature failure.

To be able to see what is causing the issue, you need to capture the setup process to a log file.

To do so, you would run the setup from an elevated command prompt as follows:

  • Exchange2010-KB4487052-x64-en /lxv c:\installsLog.Log to generate Log file

In this example, what stood out in the log file at the bottom was the following:

DEBUG: Error 2826: Control BottomLine on dialog FatalError extends beyond the boundaries of the dialog to the right by 5 pixels
The installer encountered an unexpected error while installing this package. This may indicate a problem with this package. The error code is 2826.

You might think that there is a problem with the Rollup and re-download it but the first thing that came to mind was the execution policy on PowerShell.

You can do so by launching PowerShell elevated and running the following command:

  • Get-ExecutionPolicy

As you can see it is set to restricted. This was changed to unrestricted and you can do so using the following command:

  • Set-ExecutionPolicy unrestricted

Accept the change and now launch your setup again from an elevated prompt and it should succeed.
