Deployment Workbench: Windows Imaging Error

I just installed the Windows AIK for Windows7, and MDT 2010 on my 64-bit Windows 7 Release Candidate system, and attempted to open the Deployment Workbench. It opened just fine, but when I selected the Deployment Shares node in the snap-in, I got this error: “The file C:Windowssystem32wimgapi.dll(version 6.1.7100.0 (winmain_win7rc.090421-1700)) is older than the installed Windows Automated Installation Kit (version 6.1.7600.16385).  Please remove the C:Windowssystem32wimgapi.dll file so the proper one is used.

I am unable to remove the file, or replace it with the newer AIK one, due to a lock on the file (my guess would be that it’s Windows System File Checker).

Most likely, the solution (or at least it might help) would probably be to upgrade to Windows 7 RTM, but I’ve been putting that off for so long, what’s a couple more weeks? 🙂 I just wanted to document this error / scenario in case anyone else comes across it.
