Use dumpbin to check if a PE file (dll/exe/…) is x64 or x86

Posted by jpluimers on 2017/05/04

Boy I wish I had known this long ago:

You can use DUMPBIN too. Use the /headers or /all flag and its the first file header listed.

dumpbin /headers cv210.dll

‘find’ can make life slightly easier:

dumpbin /headers cv210.dll |find "machine"
        8664 machine (x64)
