System.EnterpriseServies.Wrapper.dll missing in Powershell Work Flow

Question

I run Server 2008 R2 as a workstation (mainly to get Hyper-V IIS 7.5). I’ve been playing around with this system for a while and it’s hardly pure! ;-)

Today, I loaded the latest set of patches, and took the reboot opportunity to add the rtm version of PowerShell v3. I duly removed the PowerShell V3 beta, applied the monthly patches, rebooted, then added the new version of PowerShell and rebooted again.

However, I now have an issue: Anytime I try to run a workflow, I get:

PSH [C:\foo]: Provision-AD # Run the workflow The workflow ' Provision-AD ' could not be started: Could not load file or assembly 'System.EnterpriseServices.Wrapper.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Answer 1

The solution was easy. I did a re-install of the .NET Framework 4.0 and all is now well!
