You are on windows xp so ignore anything about Virtual Store folder. Probably just fine 1.6 is based on 1.4 not 1.5. (1.6 IS compatible with XP, I hope you've tried it since the initial switch to VS2012 compiles) -- No offense, but upgrade jeez. What is the exact error. Saying C++ error is a little too generic to even understand what the error is. You probably don't have the necessary runtime installed from Microsoft is all.
