If you get the this while running postreflect command on Vista:
postreflect e:\Windows c:
0x0000007F - Failed to GetProcAddress on DiOfflineReinstallAllUpdates
you have to start the Windows Pe Tools command promt as Administrator. The paths are updated and the error "failed to getprocaddress on diofflinereinstallallupdates Failed: Error = 0x0000007f" is no longer present.
After running the PE Tools Command Prompt as administrator the promt should start at C:\Windows\system32 folder.
