After sending the previous first post back to origin, here the necessary information:
So you are saying you have removed windows 7 as the build platform?
Also as I am sure you are aware MS prohibits redistribution of AIK and windows components.
Believe you should investigate using the PSC wimcaptex approach if you want to remove dependency on AIK components.
To be correct:
WimCaptEx still (?) also uses wimgapi.dll (and for mount wimmount.sys and wimserv.exe). But they are copied from your Win7 source CD, which you own legally.
