How to remove UFT concurrent license

I had a concurrent licesne with UFT 12.51. I then uninstalled that version and installed UFT 14.51 trial version. When trying to run the 14.51 trial version, it automatically validates the license of 12.51 version thereby giving me an error that "Cannot connect to license server. Check network connectivity or license compatibility."

I want to delete the license details completely. Can anyone kindly help me out. 

  • Have you tried forcing UFT to look locally 1st:

    Select Start > Control Panel > System > Advanced System Settings (Select the Advanced tab).
    Select Environment Variables, then select System Variables > New.
    Enter the information which follows:
    Variable name = LSFORCEHOST
    Variable value = LOCALHOST
