What I tried

Specify Microsoft DirectX SDK (June 2010) in the include directory for the VC ++ directory,
I tried both (x68) and (x84) of the lib file in the reference directory, but I can't open it.
Both of the above .lib files are in the same folder, and only the latter cannot be read.
I would appreciate it if you could tell me the cause.
