Windows 7: Property Handler works in Explorer but Not FileOpenDialog?

Question

Working on writing a custom property Handler for our custom file type in windows 7. I have installed the Windows 7 SDK and built the sample Property Handler. After registering

Answer 1

OK, figured it out. Here is the deal. My app is 32 bit and I am on a x64 system. Because the PropertyHandler is written in x64 to support the shell out of process. But for the file open dialog it needs to run inprocess, so the x64 dll can not run. I confirmed this by creating a quick x64 app and the fileopen dialog works the same as the OS. Hope this helps someone else in my shoes later on, hate answering my own question, but don't want people wasting NRG on this one as I found the solution.
