you have installed without the soundsets and the program is looking for the soundsets from the disc. It is possible that the discdrive is untypical and that it can be identified from the product.
My idea to reinstall it and to make sure that you have installed full version with all sound file...
Hi I have Music Maker 15 – And Video Edit Pro 15 which works fine. I was able to run Music Maker 15 on Windows 7 for months. But then had to re-install Music Maker. But every time l opens it say “please start application with Administration privileges once”. I click OK the pop up “please insert the Magix Music Maker installation CD-ROM and restart the program. I did this load of time with no joy. Also re-installed it again maker sure everything installed. Can anyone help please, as l said Video Edit Pro works fine? Thanks Ravhel
