Hi, Every time I start the parallels version 13 application it prompts me for an administrator name and password to "begin the installation", however it is already installed. Then after providing the info a popup comes up saying "removing the previous version..." then parallels starts. Has anyone else had this problem? I have contacted support and there response is "upgrade to version 14" !! What the heck? I've only just paid for version 13 two months ago! Seems like a simple fix however support doesn't want anything to do with it. Any help would be greatly appreciated. OS = 10.13.6, parallels version 13. thanks.
