Automate custom Windows Vista installs with vLite

WIM Filter Error Window

This window will pop up if you have already installed the WAIK file but vLite cannot find the wimgapi.dll file. Find the x86 version of the wimgapi.dll file in the folder where you installed it and copy it to the vLite root folder. The x86 version is required even if you are running the 64-bit version of Windows Vista.
