Install Geekbuddy

I have uninstalled and reinstalled new version of Comodo. Have used revo to uninstall it and searched for any files for both Comodo and Geekbuddy.I have tried everything to install Geekbuddy keep getting error 1316 specified account already exists. I got this error before I reinstalled Comodo and the same error after. Searched everywhere there is no Geekbuddy anywhere. I have C drive and D drive.
