I've no idea. I did not recognize immediately, but then I found that the XnView Shell menu disappeared from the explorer.What has changed from the last time you had success using Xn shell extension?
Yes. I'm using x64 OS. Installing a x86 DLL is not working. Most of my applications are x64.Are you sure you're using x64 version on x64 OS?
At the beginning I thought it was the antivirus, so first I tried to deactivate, then to remove it... without any results. I do not use any other security program.Do you have any advanced security software like ZoneAlarm working which can potentially silently block your register attempts?
I'm sad.
