One of my customers wanted to know if they had really built a 64-bit application for their cluster. After all, we run WIndows HPC Server on a 64-bit server OS, so why not take full advantage of it?
I had a few minutes before I had to get back to them so I thought I’d try to polish the answer a bit. Here’s what I told him: “Dumpbin is your friend.”
Here’s what I then provided as a really simple ‘tool’. A one liner actually. If and only if you have
C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\amd64
in your path. See my blog on compiling with Visual Studio from Powershell. This works fine from the old command line shell as well.

A magic machine indeed! You can get dumpbin with any version of Visual Studio. If you don’t have a commercial version go to http://www.microsoft.com/express/ .
Well short but I hope you find this to be a sweet hack.
