Earlier I installed Parallels 9 on my MBA and in Windows got the famous blue screen and forgot about it.. Now I need to install it again but I have no luck. I download the file as the original document suggests and then I click the file. The file says it wont install until I install via the dmg file which I do. Spiral into abyss starts. Click the dmg -> the dmg says "install the dmg". I click the dmg and it says "install the dmg". What can I do to install my legally purchased software?
