Answer 1

For DLL loading problem, I suggest you to use the Dependency Walker tool. It has proved to be valuable when dealing with such problems as it will show you the exact problem.

If you own Visual Studio 2005, you can find it in C:\Program Files\Microsoft Visual Studio 8\Common7\Tools\Bin\depends.exe.

Update:

MSVCR90D.DLL is the debug version of the Visual C++ runtime 9.0. It should only be used for debugging purpose. I strongly suggest to build a release version of your library in order to avoid the DLL loading problem. However, if you absolutely need to deploy the debug version, you will find all the required DLLs in C:\Program Files\Microsoft Visual Studio 9.0\VC\redist\Debug_NonRedist\x86.
