Thanks for the info. Unfortunately this info is not (or if, then maybe any way in a tricky way) available when I want to click the BUY-button of Version 13. In other words: I have upgraded to High Sierra. After upgrading I noticed that Parallels 9 is not running anymore. Since I have already Parallel 9 I bought Parallel 13 as an upgrade Version, but it is not running. What can I do now to solve the problem? Hopefully there will be another solution than to buy a new Parallel 13 Full version, I will be extremly disappointing if the money for the just bought upgrade Version will be lost.
