i am getting a message to update vegas Pro 17 and the file gets downloaded ok, (688mb). But when I hit install, a message pops up and says" The installer is unable to update vegas Pro 17.0 while it is running". But if I close vegas, it also closes the installing update box that is displayed. I have down loaded the program from your support web site with vegas not running, and still give me the same message, if i click install, " The installer is unable to update vegas Pro 17.0 while it is running"
