• Visual C++ windows.h not found...

  WOW, I can't believe this information isn't easier to find.  I downloaded and installed Visual C++ 2005 Express, and then downloaded and installed the Platform SDK SP2.  NOTHING WORKS!  The Directories are not found and there is no apparent way to set them.  Apparently users have found a hack to make it work, but this is crazy.  It seems like the first Microsoft person to install this would notice that it doesn't work an ...Show All
