I pieced together a WinPE by building a MSDART ISO, then integrating A43 file manager as a basis for the interface and integrated some remote connectivity support as well as some hard drive encryption features provided by the vendor of our encryption solution, and also the files from a WIndows 7 repair CD that are required to repair Windows startup issues. This all works fine on 32 bit OS, but some of it doesnt work on 64 bit installed OS (specifically, the Windows 7 repair components need to match the architecture apparently).
I'm not all that experienced with building WinPE from scratch and have only rudimentary knowledge of the Windows AIK (enough to mount WIMs and modify them) so I apologize I ask some stupid questions here.
In order to get the 64 bit Windows repair utilities working from inside WinPE, i had to build a 64 bit MSDART ISO, but from within that environment i cant launch any 32 bit apps (A43 doesnt work, encryption utilities dont work), and i get an error that states "the subsystem needed to support the image type is not present".
From some searching on the internet, it sounds like I need to integrate WOW64 support into my WIM somehow? What i'm looking for at this point is advice on how to accomplish that, or if there's a better way to run 32 bit apps inside a 64 bit PE .
Thank you sirs and madams.
