    You can always go through the computer using windows explorer and delete any directory relating to 3Cx and then go into the registry using Regedit and search for 3CX related entries.

    Be VERY careful in the registery if you haven't been in there before, make sure that it is actually related to 3CX and not a word that contains the characters "3cx" within before deleting anything! You can really screw up your computer if you delete the wrong entries, I'm talking complete reload of the operating system screw-up here.

    Are you having problems trying to re-install the new version? What issues is the computer having the way it is now? Is the old version still starting up?

    Re: uninstall problem

    So after deleting everything is there still a 3Cx process running when you open Task Manager? At what point do you get the message, when you first boot up, or at some point later?

    Deleting the registry and program files is not enough,

    There are assemblies to be deleted as well.

    If the installer stopped at stopping services, and remains like that, it clearly shows that some services could not be stopped. So next time go to task manager and kill the processes from there. Then you will see that the installer will continue.

    Now to fix your machine you need to do the following

    Go to

    http://wiki.3cx.com/documentation/general/installation-checker

    Download the installation checker to see what's still in the system.

    Then Follow the guide to the letter and reboot the machine.

    Then install 3CX Phone System again and the installer of V8 will fix your setup.
