I'm trying to update Growl, however App store says "To update this application, log in with account which was used to buy this application". The thing is that i don't have any other Apple ID. Is it possible to find out what account was used to bought this app?

All app downloaded from Mac AppStore(MAS) contain a receipt inside their app bundle (example: appname.app/Contents/_MASReceipt/receipt). MAS will scan this file to check whether the new version is available. You can use this application (Find Any File) to search any receipt on your drive: http://apps.tempel.org/FindAnyFile/

To make the AppStore forget the old credentials with which an app was downloaded, you must remove the To do this:
Quit and restart AppStore, then find the application you want to update. The button should now say "Free" or "Install" instead of "Update". Clicking it will update your app to the latest version, doing so as the currently logged-in Apple user. |

It's probable the developer of that app (growl) has used the same bundle ID so that the app store version and the downloaded version appear the same to the app store. Basically, you may not have even "bought" the app, but downloaded it. |
