problem with visual c++ 2010 express and seven

[ppippus]

Hi


I have a problem with c++ project (that includes many files) because it is not compiled by visual c++ 2010 express.
I open the c++ project, it is converted but if I run the compiler a pop up window error appears:

""Unable to start programc:\...\Win32\proj\actor\.\..\..\lib\release\actor.lib

the specified file is an unrecognized or unsupported binary format"


can someone help me?

If I Use visual c++ 2008 EXPRESS the same source file is compiled succwsfully.


thanks
