Hallo, mein Norton verhindert das update von thunderbird auf meinem PC.
Ich kann thunderbird nicht mehr starten.
Wer weiß Abhilfe. Danke
are you running Norton Secure VPN?
yes, i do
Fix Internet connectivity problem with an app or a program after connecting to Norton VPN [here]
Did you try thunderbird.exe with Secure VPN - Split Tunneling function?
Or, did you try Thunderbird with Secure VPN off?
