For 5.2.0, like others I was not able to successfully start it. Fixed it by going to my roaming app data folder and deleting a file called "lockfile". C:\Users\yourusername\AppData\Roaming\qBittorrent. Started fine after that.

I was able to install v5.2.0 but it would not start no matter what I tried so I reverted to the previous version which works fine as always.

It's great but can't update to the latest version 5.2.0. The file downloads but setup fails. Reverted to previous version 5.1.4. A quick bit of info, even though I've closed the programme I find that I have to go into Task Manager, search for any instances of qBittorent and end task otherwise Windows blocks the setup. 5.2.0 setup just doesn't work whatever I try.

It's a good program but I can't currently install the latest version , my Windows PC blocks the download when I try to install it. It can't identify the validity and thus the legitimacy of the file. So I can't upgrade from my current version
