Visual Studio 2015 and Pro/Toolkit Version < 4.0

Dear all,

I'm using Pro/Tookit to implementing an DLL which provides access to Creo for our main program.

The DLL is loaded by the main program via LoadLibrary() and freed via FreeLibrary().

This can happen more than once.

For a long time i used the Pro/Tookit libraries provided by Creo 1.0.

Now I updated from Visual Studio 2010 to Visual Studio 2015 and I got the issue,

that the second call of LoadLibrary() fails always on some computers.

I guess the problem are the different runtime libraries.

Can this work at all?

I'm reluctant to update to Creo 4.0, because it has no x86 support.

Thanks in advance.

Olaf
