I got the above mentioned error when i tried to install uTorrent 1.8.4 on Ubuntu Karmic Kola i386, though wine. But this error does not come if you try to install utorrent 1.8.2 or a older version. Hence i installed 1.8.2 and then updated it to 1.8.4 and it works fine. i think the latest versions have some bug in the installer part. installing a old version that doesn’t have this bug and upgrading seems to be a good work around. Note that if you installed 1.8.4 or something newer you will have to uninstall it from wine and then install 1.8.2. even then if you are getting the same error try killing wine and restarting it (wineboot should do the trick according to http://ubuntuforums.org/showthread.php?t=630811. If that doesn’t work for you just kill the two processes that belong to wine and restart it).
