Hi All, I am trying to install Movie Magix pro plus on my new computer .This program ran on Win 7 no problem but now with win10 error 1603 comes up from what i can find is that KB2721691 is not in computer. have tried to install this number from Microsoft but to no avail. This error starts when installing the program at the beginning You can accept that and continue to install but only some parts of program are not installed e.g.Menu templates,no tree structure only user defined/general/warm pan/2 menus.. have downloaded on my laptop win 10 same problems. Specs as follows:hunter GTX 1060 Gaming PC intel Core.i5-9400F 6 core 8Gbs RAM Nvidia GeForce GTX1060 6Gbs..240 SSD..Win 10 Home 64 bit. Hope you can help and thank you if you can.Cheers, Eric......
