If you have issues with your Unitrends Provided Kroll license file, note, license files are version-specific.  Kroll 7.x licenses will not work with Kroll 9.1, etc.  A new key can be obtained by actively supported customers who purchased older standalone versions of Kroll through Unitrends and have not lapsed support since that point, or those currently licensed for Enterprise Plus editions of Unitrends Virtual or Physical Appliances  Please contact Unitrends Support to initiate a request.  Processing typically requires one business day.  

If believe you were sent a key but did not receive it, check your spam or other email filtering technology as Ontrack Licensing emails have a *.INI file attachment that is commonly filtered from delivery.
