PCAnywhere x64 WinPE

I had modified my x86 WinPE to include PCanywhere and bginfo which works fine. I created an x64 Winpe it doesn't work. When I try to run it manually in WinPE i get the error "The subsystem needed to support the image type is not supported" - how can I get the 64bit PCanywhere files required for this environement? Are they available ?

(I believe WinPE 4.0 doesnt have the 32bit subsystem that would have run the current one)

Thanks
