Further to ++soonix's good questions: Are you in the 64-bit cmd.exe on both machines? You can check Task Manager, which shows cmd.exe *32 for the 32-bit cmd.exe, and just cmd.exe for the 64-bit version. Inside cmd.exe, you can also check (see here for details): run set, and look at especially the PROCESSOR_ARCHITECTURE and PROCESSOR_ARCHITEW6432: the first should be AMD64 or similar in a 64-bit cmd.exe, and x86 in a 32-bit cmd.exe; the second is only defined in 32-bit cmd.exe, and should be AMD64.

How this will help fix the problem, I am not sure... but it might point to where the difference lies.
