I have an Exchange 2007 beta 2 server. I attempted to install Exchange 2007 RTM and received a message indicating that I first had to install the PowerShell. So I uninstalled the Monad beta and installed the PowerShell. Now, when I attempt to uninstall Exchange, I get an error message indicating that ExSetupUI had encountered an error and was unable to run. I get the same error when I attempt to run ExSetup. Any ideas?

Hi, Not sure whether this will help but here is another post which shows the steps. http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=1002583&SiteID=17 My general feeling would be that a clean install would be preferable to upgrading a beta, especially as the upgrade will not be supported.
