Sorry for the very late reply, didn't get around to doing what you asked until upgrading to 1.17. Anyway, here's where versions prior to 1.16 stored the files that were supposed to be in the Users\%userprofile%\AppData\Local\VirtualStore\Program Files (x86)\BitComet folder:
C:\Program Files (x86)\BitComet
So actually the older versions didn't go through all the LUA-UAC headache and managed to write itself there. Overwriting all the required folders from the installation directory into the folder with userprofile solved the problem:
BitComet.xml
Downloads.xml
cache
rules
share
torrents
Perhaps future BitComet installers could detect if the files & folders are still at their old directory and copy it over to the new location.
Hope this helps!
After installing 1.16, all the torrent tasks are missing, be it completed or in progress torrents. The torrent file is still there in the torrent archive, but nothing appears in the "All downloads" section at all. Reverting back to 1.15 and I get back my list. Is this a bug, or is 1.16 using a different method altogether for its list? I do not want to having to add back each 100+ torrents just to seed them.
