Modify Registry to get program to show in Add\Remove Programs

I have a program that i need to uninstall to be able to upgrade.  I cannot uninstall the program because it isn't showing in add\ remove programs.  According to the software manufacture, I need to log in as the user who installed.  A user who no longer exists in my system.

I can get to all the Registry keys for the uninstall info, and I was wondering if there is a way to modify the registry to get it to show up for me.  I've already backed up my registry

    Check to see if your Program has an UninstallString, if it has all you have to do is navigate to it in explorer and run the executable.


        DisplayName    REG_SZ    7-Zip 9.20
        UninstallString    REG_SZ    "C:\Program Files\7-Zip\Uninstall.exe"
        NoModify    REG_DWORD    0x1
        NoRepair    REG_DWORD    0x1

    To remove 7-zip I could navigate to C:\Program Files\7-Zip and run the Uninstall.exe

    Also check to see if your Programs DisplayName hasn't been renamed to NoDisplayName as it wont show up in Add Remove Programs if it has been changed.


    DisplayName    REG_SZ    7-Zip 9.20       'This will be displayed

    NoDisplayName    REG_SZ    7-Zip 9.20       'This will not be displayed
