Hello community,
more and more 64-bit programs and libraries comes into our focus and very often exists the question, how to differentiate which program or library is x86 or x64. It is very easy to differentiate, if you find in the first 280 bytes the hex 50 45 00 00 4C (PE..L - PE means portable executable) it is an x86 version. If you find 50 45 00 00 64 (PE..d) it is an x64 version. You can open each program or library with notepad.
x86 (32-bit) version:
x64 (64-bit) version:
Enjoy it.
Cheers
Stefan
