FICO® Xpress Optimization Suite Discussion

[prusakov]

Hello, 

I am trying to resolve an initialization error for the optimizer library. I have a license for and installed Xpress-IVE 64bit studio, however, I need to link and use xprb facilities in a C#.Net application that is built in VS2010 and runs on IIS. 

I copied xprb.dll and xprbdn.dll to application bin folder for deployment, and added them as references.  Yet when the application calls XPRB.init(), it throws exception 

Unable to load DLL 'xprb.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Any suggestions on what could be missing?
