Question : MDT OS import problem

When trying to import an OS into Microsoft Deployment Toolkit (MDT 2010), I get the following error:

Unable to get information for WIM file D:\\Sources\Install.wim

I'm importing a full set of source files directly from a Windows 7 professional disc.  Any ideas?

Nevermind, solution is to reboot after installing WAIK:
