Windows registry key to delete software?

I just installed a new HD but I ran into a little problem. When I tried to install a patch for COD I did it wrong. I uninstalled the program and re-installed it then tried to set up the patch again. The problem is when I do that its still finding remenents of the first time I tried to install the patch so its aborting the install because its saying the 1.5 patch is still there even though it should not be. How can I get rid of all rements of a pervious installed software? Last time I thought someone told me to use the windows registry key but I can't remember how to do that.

  1. Anyone at all?
  2. Unistall the app again. Be sure to delete the game folder as well. Then run CCleaner's registry tool to clean the registry (piriform.com/ccleaner). Try to install again after cleaning your rig.

    Good luck!
  3. Thanks I'll try that. There is a way though to go directly into the windows registry key, find the packets causing trouble and delete them I just can't remeber how to do it.
  4. Is this a legit version of the game?
  5. Use this to uninstall the game, use advanced scan:http://revo-uninstaller.en.softonic.com/
  6. Yes it is and I figured it out. Thanks anyway.

    I knew you could do it through the registry editor but I couldn't remember how exactly. I looked it up and it took awhile but I found out how to do it. It was pretty easy really. This is how you do it:

    1) Click Start button > Run.
    2) At the prompt type: REGEDIT. The registry editor will open.
    3) Click the "+" next to HKEY_LOCAL_MACHINE.
    4) Click the "+" next to SOFTWARE.
    5) Click the "+" next to ACTIVISION.
    6) Right-click on the CALL OF DUTY folder and select Delete.
    7) Close the registry editor.

    Once the registry keys are removed you have to remove the game files from your hard drive. Then re-install and it should be as if the patch never happened
  9. Thanx,

    It may help to someone else, one day.

    That's why lots of people comes to Tom's forum for info and get some ideas along the way.
