Generally that error means the linker didnt know where to find the library you specified. In your project link settings make sure you add the path to the library as an "additional path." The process for doing this varies depending on your compiler.

Cheers and good luck!

ok ill try, but why would it be asking for a exclusive 64bit library?

Its not looking for an exclusively 64bit library. You said you told it to add it as an additional library...so it needs to know where to find it. Usually microsoft libraries we add are located in one of the standard paths which Visual Studio looks for it. In this case, visual studio is unable to find the library in its default paths.

when i add the additional dependency "msvcirtd.lib" i recieve a "cannot open object" error. i dont understand this error int he first place as this .lib file is located in the amd64 folder

You said it was located in the amd64 folder? Which amd64 folder? How did you know it was located there? And more specifically, why did you add the library as an additional dependancy? Once we know the answers to those questions, I'm sure you'll get a few more responses offering help.

Cheers!
