This error message only seems to occur when the 64-bit version of the WAIK is installed off read-only media (such as an ISO image).
It appears that this is caused by an entry in the Media table of the wAIKAMD64.msi file. The MSI is looking for a embedded cab file that is actually external.
There are three ways to ‘fix this’;
- Copy the source onto a writable hard disk and then run the MSI.
- Make sure that your CD ISO image is called ‘KB3AIK_EN’. This is the volume name the MSI is looking for.
- Create an MST file that alters the ‘Media’ table. Change the line for the ‘WinPE.Cab’ cabinet so that the ‘VolumeLabel’ field is set to “DEFAULT” instead of “KB3AIK_EN”. This is my preferred option.
Hope this helps.
