With having all the same issues as most here with the ver 4,0 upgrade, I have reverted back to ver 3,0 until this mess settles down a little. This morning when I powered up Parallels, I got the prompt that there was an update (build 5626 ??). I have always had issues with updating from within Parallels / via these prompts and usually end up downloading the standalone latest version and using that. Same happened this morning - the file downloaded. but when tried to install, Parallels froze. Trying to run the downloaded dmg file resulted in a dmg error (would not open). Now that Parallels is officially ver4.0, I cannot for the life of me find the standalone latest ver 3.0 file on the websiter, Through the forum, I can find a link to the old build (5608) but not the new one..... Anyone can help ?
