I think the title says it all! I wanted to open my copy of PhotoManager 17 in order to check something to be able to help another poster to the forum, to be confronted with a series of error messages, as below:
I tried the "obvious": re-ran the original installer, chose the option to "Modify"; no change.
I then completely uninstalled, using Revo Uninstaller Pro, ran the installer again, installation went without any apparent hitch, opened the app, to be greeted by the same three error messages again!!
Because i have some 8 Magix programs installed I'm a little reluctant to try the route suggested in this tutorial but that looks very much like having to be my next step. Unless any other user has ideas to try?
