LNK2022 when converting VS2010 project from 32-bit to 64-bit

Question

I am converting a VS2010 project from 32-bit to 64-bit. Compiles fine, but when it attempts to link, I get the following errors:

 1>LINK : fatal error LNK1255: link failed because of metadata errors

This project is primarily a Windows Forms GUI that is interfacing to a .dll. The .dll, which is a separate VS2010 project has compiled and linked fine.

I have been beating my head against the wall for 2 days on the problem and am at a loss of where to look next.

Please let me know of any other details that may be useful.

Answer 1

Change Struct Member Alignment to "bytes" in Project settings-> configuration Properties -> C/C++ -> Code generation.

This is because 4 byte struct alignment is not supported in 64 bit. It needs to be at least 8 bytes (8x8 =64). You can change this option in settings to get through the compilation errors. it does not mean your program will be working.
