I have a DLL created from Fortran code using digital Fortran compiler in Visual Studio 2008 on window XP. I was able to use this DLL in my Excel VBA code without any issues in my Windows 7 64-bit PC. The DLL stopped working when Intel Parallel Studio XE 2013 and Microsoft Visual Studio 2010 shell is installed. I don't have the source code to recreate the DLL in Intel Fortran. Please help me in understanding what could have happened.
I was using the DLL with other support DLLs (DFORRTD.DLL and MSVCRTD.DLL) in current working directory and specifying the entire path while declaring the funtion in excel vba.
Thanks and Regards,
