Old DLL fails in VS 2012.

Question

Hi all.

I have a project that works perfectly under windows XP and Visual Studio 2008. Within this project is an old DLL written I believe in Microsoft C++ 6.0.

 

I am now running Win7 32bit. The published project runs absolutely fine.
However, to debug the code when we run the project in VS2012 we get the error
"Unable to load DLL 'USBDIO': The specified module could not be found. (Exception from HRESULT: 0x8007007E)"

I have scoured the net and cannot find any reasonable solutions. Would anyone possibly have any idea's that could help?

Thanks all.
