When I install Latest x64 version without admin permissons. It doesn't install at all. When I install it with admin permissions, i see only desctop icon created, both AppData and program files are empty. I have UAC off in windows. Actually found that it was installed to C:\Users\User\AppData\Roaming\BitTorrent Sync. When i used admin rights. With admin rights it doesn't appear in installed apps.
