Watch your manners. Not everyone reads the whole forum and it's not an abnormal thing that the solution would be obscured under many other threads that some people might miss.
Also, you could, for example, be like me, having a comp that is not daily updated, and that's a normal thing where I come from because internet is a luxury.
And you could be missing Microsoft.NET framework on its' latest version.... or Microsoft Visual C++ Redist of certain year (note that latest version doesn't matter in this. It asks for certain version, one that might be older. I forgot which, could be 2010, 2011 or maybe 2009 if ot exists)
