HOWTO: completely un-install and re-install Izot CT

    Un-install:

    1. If needed, create a backup of your Izot projects (however, the projects should not be affected by the re-installation as long as they are not located in the LonWorks folder)
    2. Return the Izot Net Server and CT licenses using the Echelon License Wizard (if applicable)
    3. Uninstall all LonWorks software from the computer using Control Panel-Programs. This would be any programs containing Echelon, LonMark  or LonWorks in their name.
    4. Delete or rename any LonWorks folders on the computer (typically c:\Lonworks and c:\Program Files (x86)\LonWorks)
    5. Open the Windows registry using regedit.exe and browse to HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\LonWorks. Rename the LonWorks registry folder
    6. Restart the computer


    You are now ready to re-install

    1. Run the Izot CT installation with Run as Administrator
    2. You should now be prompted for the installation path. Keep the default c:\Program Files (x86)\LonWorks
    3. Restore the backups created in step 1 above if necessary (the GlobalDB might have been preserved depending on its location)
