That's what you've already posted. I mean, can you find any file in C:\Users\[username]\AppData\Roaming\Cyberduck\CrashReporter?

Sorry. I did not find any crash report? and did not see C:\Users\[username]\AppData\Roaming\Cyberduck\CrashReporter? I saw C:\Users\[username]\Roaming\Intel\Wireless.

That seems to be the wrong location. To easily find the Cyberduck AppData folder you can run the command %APPDATA%\cyberduck by pressing the Start button and the choose Run... After pressing OK an Explorer window should open showing the Cyberduck settings folder. From there you can navigate to the CrashReporter folder.

Hi yla,

Thank you for providing the instruction in retrieving the crash report. Please see attachment for reference.

Thanks for providing the crash report. We are aware of this issue but it's pretty rare and we were unable yet to find the cause. Will need some more investigation.
