Looking in my ,Add and remove programs, in control panel windows xp sp3, I have 3 versions of Microsoft Visual C++ Redistributable. They all have different numbers, 8.0.59193 and 8.0.56336 and 8.0.50727.42. I installed one by your requirements when we were trouble shooting last week. At that time I only had one version. But since then I have had to uninstall and reinstall my 3 airports.FSX/ACC. Anyway my question is, Is this being downloaded with each airport ?
