if it happens that in your IDE (my MVS 2010) is in this error:
1> c:\documents and settings\admins\desktop\debugsymbols_source\DebugSymbols\stacktrace\stdafx.cpp : fatal error C1902 : Program database manager mismatch ; please check your installation
2> c:\documents and settings\admins\desktop\debugsymbols_source\DebugSymbols\symbols\main.cpp : fatal error C1902 : Program database manager mismatch ; please check your installation
happens because for some reason thath I do not have time to find ( I have 5 compiler, 2 of which them only begin with batch) mspdbsrv.exe is not loaded into memory.
to fix in two seconds the problem you can go in the path of mspdbsrv.exe (for example C:\Programmi\Microsoft Visual Studio 10.0\Common7\IDE) , create a bat file and write "mspdbsrv.exe -start -spawn", it will work.
