qbittorrent breaks update or deinstallation of nmap on windows

[buegeleisen]

platform: windows 7 64 bit
qbittorrent 2.9.7
nmap (with zenmap gui) 6.0.0/6.0.1

when trying to update my nmap-installation while qbittorrent was running it broke because it was unable to overwrite libeay32.dll and ssleay32.dll (both under C:\Program Files (x86)\Nmap) due to them being locked by another program.

checking it showed that these two files are used by qbittorrent. after closing it the are deletable again.

qbittorrent lies under C:\Program Files (x86)\qBittorrent.

is there any special reason why qbittorrent is using other program's libraries?

the condition is repeatable.

persists with 2.9.10.

i'll aditionally attach a csv (tab separated) with process explorer's output of dll's opened by qbittorrent.

Those are OpenSSL libraries and yes, qBittorrent uses them. However, I have no idea why it would be using those from mmap folder instead of those in the qBittorrent folder. Could you confirm that the same libs are present in the qBittorrent install folder?

[buegeleisen (buegeleisen)]

the only files in C:\Program Files (x86)\qBittorrent are qbittorrent.exe and uninst.exe. i just installed installed qbittorrent on a vm with a fresh windows 8 release preview (64 bit), they are not there, too.

[buegeleisen (buegeleisen)]

well, i checked today after installing 3.0.4, looks like qbittorrent stopped using other program's dll's.

so i guess this bug can be closed.
