Komodo saves all of it's settings in it's profile folder, if you want to start Komodo with the default settings there's 2 things you could do:
When Komodo looks for the profile folder and cannot find it it will create a new profile folder with the default settings.
Before following these setps please ensure that Komodo is not running.
You can set the location where Komodo looks for its profile folder with the KOMODO_USERDATADIR environment variable. It's value should be set to the parent folder that you wish for Komodo to look in.
"C:\Program Files (x86)\ActiveState Komodo IDE 9\komodo.exe"
You want to completely start over, for whatever reason. It's as simple as deleting your Komodo profile folders and starting Komodo.
First, locate your profile folders and make a backup of them, just in case. Note I'm saying "folders", implying more than one. This is because Komodo creates a profile folder for each version of Komodo you used. So if you used Komodo 9 through 9.2 you'll have 3 folders: "9.0", "9.1" and "9.2". You need to delete all of these to fully reset your settings as Komodo inherits it's settings from the previous version.
