Hello DakaPC5,
I also faced the same problem. but as per the suggestions of Anit_kumar if we follow the steps it will work.
We just go through the following process:
1)Go to the folder cf_install\cfusion\lib and open the file license.properties.
2)Enter the serial number at , sn= and save the file.
3)Restart ColdFusion 10 Application service.
4)Log in to the ColdFusion 10 Administrator and check the edition.
We need to restart coldfusion 10 Application server.
Regards,
Biswajit
