I have tried to install this update multiple times, and it will download. But, each time it tries to install, there is a message that the repair function must fix an error. The update never installs. I am running Version 19.4.0 (54962) of Parallels. Is this a known problem, and is there a solution?
Report it using the MS Feedback Hub. There are lots of others who have the same problem. There are now at least 5 threads here reporting that problem.
