I have upgraded a Windows 7 Pro system from 2013 to 2013R2 to test it out and it seems to install and work just fine until I reboot the system. Once I reboot the system the main service crashes with
In the System log
The Symantec System Recovery service terminated with service-specific error %%-2147221005.
In the application log
Error EC8F1775: An error occurred while starting Symantec System Recovery service.
Error EC8F1772: The following component is not installed correctly: Symantec.SpnRegistration.
Error EBAB03F1: Following Operating System error occurred while performing requested operation: 'Invalid class string.' (UMI:V-281-3215-6005)
I can repair the software and it works after the next reboot but if I reboot after that it starts failing again.
Found this for an older version
REGSVR32 "<drive:>:\Program Files\Symantec\Symantec System Recovery\Agent\spnregister.dll" (64 bit and 32 bit versions).
This seems to fix the problem.
