I downloaded the FREE version of Music Maker and am asked for a serial number to activate. How do I activate this program I was not given a serial number?
by having a Serial number would suggest that you actually purchased Music Maker .
since you didn't buy Music Maker ,....Music Maker will run in "Free Mode" , by default . ( ignore the activation box )
Some of Magix programs , have Trial periods , such as ACID Pro 8 , Samplitude . these programs Do come with a Special Trial Serial Number . "Music Maker Free" does NOT have a Trial period . you can use "Music Maker Free" for as long as you want ,...No serial number needed .
Is the dialog box popping up asking for serial number/activation?
If so you can ignore this, or if you have a previous version of Music Maker installed you can activate the effects, synthesizers and soundpools from that version/edition by entering its serial number in the dialog box, shown.
. . . . do the "Features" get included too . . . .
AFAIK that depends on the feature and the version of MMM they are installed with, some are locked to a specific version of the program or are not compatible with the latest version.
I have also found that MMM 17 (2010) features/soundpools/instruments etc cannot be activated, however later versions of MMM can.
