This error comes because the “Protexis Licensing V2" services in Windows was disable. For solving this error you can do this:
Click Start, then point to Run and type: services.msc at the box
find “Protexis Licensing V2”, then start the service. After that change it to Automatic
Close the Services window, then restart your computer. That's all, now you won't see that error anymore.
But If you can't find the “Protexis Licensing V2" service, you can download from here:
Copy PSIKey_2.dll and the PsiService_2.exe, and paste them to C:\Program Files\Common Files\Protexis\License Service
Right click on file REG_Protexis_licensing_service_V2_fix[2010]-ihecker.reg, then choose Merge
After the service installed, edit the service from Computer Management, then restart your computer.
