I recently purchased the Humble Bundle that contained 5 programs from Magix, and I've ran into the same issue when I tried to install all five of them. The installer opens up, and it tries to start, but promptly stops at 0%, and whenever I retry it the same thing happens. I have tried running the Magix installer from documents and it displays the error "This app can't run on your PC", i've tried resetting, downloading straight from Magix official site instead of Humble Bundle, and running the same .exe on another computer of mine, and I get the same message. The products specifically are:
Magix Music Maker (V4)
VEGAS Movie Studio 16 Platinum
SOUND FORGE Audio Studio 13
ACID Music Studio 11
Video ProX 11
Plase help.
