Toolset v100 DLL running in v120, Access violation when running with debug

I am running a third party DLL using LoadLibrary. I think the dll is build in platform toolset v100 while im running v120 and dont have v100 on my machine. When i "run without debug" in debug and release everything works perfectly but when i try and debug it every dll function i call gives me a Access violation. I have recreated my project on a separate machine running VS2010 and everything works, including debug.

Is there a way to solve this so that i can debug the project without installing VS2010 on my machine?
