I had a weird problem with the update mechanism of Thunderbird. When you restart Thunderbird for an update an error message shows up and says that it cannot do the update and closes the problem. But then it starts the program again, because you said you wanted to restart it. When starting the program it tries to perform the update and fails again. This goes on and on…
After a while Mr. Google told me the answer:
When the webcam software from Logitech is running the update fails. Don’t ask me why, or what the connection is…
When you stop the “Logitech QuickCam Software” the update goes smoothly without problem.
My recommendation for all Thunderbird lovers which own a Logitech Webcam:
- Stop the Logitech software before you update Thunderbird.
If anyone has an idea why… please let me know!
