Thanks for the prompt response! I installed the debug version and looked at the log files. Seems you were correct about the possible cause being special characters in the folder names. I had one folder named like follows: Code: Helsingin Sanomat [la, 03 maalis 2012] (9) To me it looked like the application went into an endless loop. Here is an excerpt from the log file. There is a strange path string: 11 "/././././././././././." that is getting longer and longer.

But I guess the problem is caused by the square brackets in the folder name. When I removed the problem folder the update started working.
