I realize Music Maker 7 is obsolete and was never intended to run on Windows 10 (or Windows 8, or Windows 7 and probably not even Vista--it didn't even work correctly with XP SP3). . . .but I installed it anyway. . . .and of course it doesn't work. I didn't think it would hurt to try but now I can't remove it. When I attempt to uninstall, a dialog box opens to inform me "This App can't run on your PC. To find a version for your PC check with the software publisher." The result is the same whether I use Window's uninstaller (settings > apps & features > [select from list] > uninstall) or run unwise.exe directly from C:../MAGIX/MM7/unwise.exe. I have not tried any third party uninstallers.
