I installed visual studio 2010 ultimate version and everything worked perfectly fine and my development environment worked well.
However I had a recent problem in which every piece of code gives me the error about header files not being found like iostream
stdio.h
conio.h
etc.
I pinpointed the problem to it being caused by me uninstalling visual C++ express 2010 that I had installed previous to the installation of the visual studio 2010.
I tried to completely uninstall and install Visual Studio but it seems some files are always left that I cannot track. I used this link and the answer marked right over there to no avails. Can anybody advise me how to get it right without formatting the whole system.
