Ed, I don't want to muddy the water with bad info....however I think I read on the Cakewalk Sonar forum that it matters the sequence of installation of Win 7, for Sonar to play well with Win7. If memory serves me well, Cakewalk recommends that you instal 32 bit FIRST, the 64. PLEASE investigate this yourself before you uninstal, and then reinstal, Don't rely on my faulty memory banks. Hope this helps
