Did you include TC matching your WinPE's architecture? In other words, if your WinPE is 32 bit, did you include TC 32 bit, and if your WinPE is 64 bit, use TC 64 bit?
WinPE doesn't include WoW64 (Windows on Windows x64) by default. Unfortunately I don't know if it's possible to integrate it (and how) because I didn't play with WinPE too much so far.
