Hi. After I upgraded my OS, Comodo stopped working for some reason. I couldn’t start it so I couldn’t export my settings. So I uninstalled and reinstalled and it works fine now. Problem is all of my settings are gone. Before uninstalling I copied program files\comodo folder to another location, so is there a way to get my settings back? I had TONS of custom rules, etc. on it 
Hi armagan
Welcome to the Comodo forum
The only way to get your settings back is if you exported them before uninstalling. You right click the CIS tray icon and choose configuration → manage my configurations → Export. You then name it whatever you want and save it wherever you want to. After install you import it from the saved location. This retains all of your former settings.

Remember to save the settings in a folder that is not part of the Comodo Firewall or Comodo Internet Security folder. Then you may loose your settings.
I made a separate folder for my back ups.
