I asked the developer of qBittorrent about this, and he told me to come here instead.
I've been using the portable qBittorrent for 2 or 3 versions now, and in none of those versions has the Auto-Shutdown function worked for me. When I set the program to auto-close upon completion of the downloads, nothing happens. The same is true when I set it to shutdown the PC.
Is this something intentionally disabled in the PA version, or is it a bug?
Cheers!
All our launcher does is move qBittorrent's settings to/from its registry keys and the LOCALAPPDATA and APPDATA locations it uses and adjust the qBittorrent.ini file to update paths as you move PCs. While running, qBittorrent runs as normal.
Sometimes, the impossible can become possible, if you're awesome!
