Q: I'm trying to build and run the C# samples (http://www.pdftron.com/
downloads/PDFNet.zip). I'm using Visual Studio
2008 on vista 64 bit. I've built the projects, created my own
projects, and the builds seem to be successful. However, when I go to
execute the .exe I get an exception that this isn't a valid win32
program (image).
I'm assuming the unmanged code (dll), or assembly, (PDFNet.dll) that
I'm using as a reference for the PDFTron functionality isn't correct
or is corrupt in someway. Any ideas?

A: The problem is that you are trying to run a 32-bit DLL in 64-bit
mode.
In case you would like to run the same DLL on both 32-bit and 64-bit
machines you can select the application to run in 64-bit WOW mode
(which can be selected in Visual Studio project settings).
Alternatively you may want to use a 64-bit version of PDFNet (for .NET
- http://www.pdftron.com/downloads/PDFNet64.zip; for C/C++/JAVA -
http://www.pdftron.com/downloads/PDFNetC64.zip) or deploy a platfrom
specific DLL as part of your application installer.
