Possible solution:
Boot into "Safe Mode" by pressing F8 during the boot cycle.
Go to Start > Run and type: regsvr32 regwizc.dll , and hit enter.
Then go again to Start > Run and type: regsvr32 licdll.dll , and hit enter again.
Apparently, the above files became unregistered due to malware
or registry corruption.
