I have an old installation disc for Magix Notation 2. I bought a new computer recently and tried to install it. (I've managed to install it on all past computers since I bought it.) On trying to run start.exe I get that I do not have permission to run this.
Notation is 18 year old software and will not run on a modern OS like Windows 10 due to very significant differences between the Windows versions it was compatible with - Windows 2000 to XP and the current version of Windows.
I created an account so I could reply to this. You should be able to run it inside VirtualBox. (And if you happen to have created a .iso of the installation CD, I'd love to borrow it so I can convert my old .mnt files to midi !)
