I need your help with a Parallels update: I have a Mac OSX Yosemite (10.10.4). When I start Parallels I see a message saying me that "New version is available" (see the picture here below): But when I click on "Install Update" nothing happens. There's a sort of "crash". And when I start parallels the next time the update message is still there. Anyone can help me? Thank you.
