I had same problem today after reinstalling GTA. I reinstalled Microsoft Visual C++ Redistributables (especially 2005 SP1, 2008 and 2010), in my case both 32 and 64-bit versions - I've got 64-bit Windows 7. And, after reinstalling, do not forget to restart your PC.

If your Windows is 64 bit, you should install too:

Of course it is possible, that you don't have for example only one of this packages (or 2005 without SP1), but it makes difference.
