Serial number of Soft-eLicenser (virtual license container) not unique

  • Licenses for many Steinberg programs are stored in the so called Soft-eLicenser, a virtual license container on the hard disk.
  • Each Soft-eLicenser has a unique number which is required for the software registration and license activation. 
  • The Soft-eLicenser is represented by a hard disk symbol in the eLicenser Control Center - the license managing tool used by all Steinberg programs.
  • The eLicenser Control Center can be found under Applications (Mac) resp. Programs (Windows). 


On trying to activate a license an error message comes up:

'Unfortunately, the serial number of your Soft-eLicenser is not unique'

The current versions (starting with can regenerate the invalid Soft-eLicenser number automatically and the activation of a license should work after the installation.
