4.1.6 Windows 10

If on linux, libtorrent and Qt version

(type here)

What is the problem

After installing qBittorrent will not startup

What is the expected behavior

qBittorrent will start and run

Steps to reproduce

successfully install 4.1.6

Extra info(if any)

(type here)

[LAUVz]

Same here it just instantly goes in not responding and then just closes.

[LittleVulpix]

Yeah it's broken.

[Destroyarr]

Same here x64
w10 1809 latest patch level

[thalieht]

Maybe unimportant but which win 10 version? I'm still on 1803, no problems with starting 4.1.6.

[a4h7]

1903

[LittleVulpix]

1703

[Neocridas]

Same here with me (1903)
Workaround:
run qbittorent in administrator and it works.

[malinwa001]

Same here, work around did't work.

32 bit versions is working well.

[LittleVulpix]

Mine already runs as admin, and well, it doesn't run. For the time being, back to 4.1.5 which works no problem.

[njscorpion]

I am using Win 10 Ent x64 build 1903.18362.86 after i updated to QBT 4.1.6 it was working for sometime but every time i had start it twice as the first time it was crashing. But now it opens for few seconds and then crashes.

[Chocobo1]

I suspect it is the same as #9667 (comment)
So you'll need to edit C:\Users\<username>\AppData\Roaming\qBittorrent\qBittorrent.ini and change DownloadTrackerFavicon=true to DownloadTrackerFavicon=false save and restart qbt.

Note: You only need to edit the ini if you upgraded from older qbt version. If you did a clean install then no editing is required.

[MoralisRubric]

Having the same issue, with win 10 (1903) x64.

@Chocobo1 suggested solution does not working for me.

[Cologler]

@Chocobo1 suggested solution does not working for me too. fixes by back to 4.1.5 🙃

[TiagoJSilva]

I'm having the same issue in Windows 7 x64. qBT 4.1.6 starts loading, takes the usual long time to load all my torrents, then "Application not responding" without even painting the window. Went back to 4.1.5 although the fix for checking all files at the same time was very important for me.

[legithubuser]

It doesn't even want to install on my WIndows 10 64 bit system. I get a "can't write file.exe" error.

[ghost]

I have 2 VMs running Windows 10 on it. Both are very similar configuration and same version of windows. Both just updated to 4.1.6 x64 and both had crashes right after startup. For one of them, the fix suggested by @Chocobo1 worked perfectly. For the other one, the fix or running as administrator has not worked. I'm downgrading now. The exception from Event Viewer does not provide any useful information:

[TiagoJSilva]

My issue was solved with the favicon fix in qbittorrent.ini

[sledgehammer999]

Those still having crashes can you try the following build?
Just extract and run in any folder. (or you can overwrite the installed files)

Link: https://builds.shiki.hu/temp/qbittorrent_4.1.6_x64_for_issue_10581.7z

[LittleVulpix]

Is there source for this build / commits? One can never be too cautious running random stuff from the internet... Thanks!

[sledgehammer999]

@LittleVulpix in case you didn't know I am the admin. I make the official builds and releases.
This particular build is the exact same source as 4.1.6, but with the /guard:cf compiler/linker option disabled. (I have run into issues in the past with it).
If this doesn't work, I'll have to try something else.

[LittleVulpix]

@sledgehammer999 I didn't; my bad. I tried it in my test system, but the problem is the same. It also takes a very long time to init as opposed to 4.1.5 which launches in a few seconds. 4.1.6 takes about 30 seconds and then it crashes.

[sledgehammer999]

Can you try the following build? It is v4.1.5 but with all the new libs used in 4.1.6. I am trying to figure it if the problem is in the new qbt code or in the new libs.
Link: https://builds.shiki.hu/temp/qbittorrent_4.1.5_x64_for_issue_10581.7z

[LittleVulpix]

That one crashes as well. Though, it just "disappears silently". I don't get a windows "crash" message anymore. Nonetheless, it does not work.

[ghost]

@sledgehammer999 both the files you attached are still causing crashes on my machine. Looking at the crash report there's nothing even remotely useful in there. If you have a debug build you want me to try I'll be more than happy to test it.

[sledgehammer999]

Looking at the crash report

Wait! You get a window of qbt with a stacktrace? If yes, can you post it?

[LittleVulpix]

I think he means the windows "reliability" crash report, stuff like:

Problem signature
Problem Event Name: APPCRASH

Which, as he noted, tells you nothing.

[sledgehammer999]

New build. It is v4.1.6 but with the libtorrent and boost version used in v4.1.5.
(that libtorrent version fails to build with latest boost)
Link: https://builds.shiki.hu/temp/qbittorrent_4.1.6_x64_for_issue_10581_v2.7z

[LittleVulpix]

This crashes as well.

[ghost]

This crashes as well.

Same. And yes I meant the same crash report that @LittleVulpix posted.

[theswagler]

JNavas2- I didn't mean to rile anyone, just an old-school C++ programmer's two-cents.
In your opinion, which latest version is the best?

[JNavas2]

@theswagler Sure, no offense taken, none intended.

I currently use and recommend qBittorrent 4.1.5 64-bit on Windows 8.1 Pro.

FWIW, I cut my software teeth on Autocoder (like Assembler). I can now program in well over 100 languages. I've taught software engineering and quality management; I've managed large, complex software projects; and I've released public Android apps.

My principal objections to assembler and C++ include lack of checking and typing. My current language recommendation would be Rust.

[theswagler]

JNavas2- I'm a mech/arch designer that enjoys C++ as a hobby.
Here's apps I've written since 2004: https://swaglertools.cf/
My flagship is Image Draw, it utilizes GDI+ to create 2D layered projects similar to Photoshop, but in a CAD environment.

[bviktor]

To me 4.1.6 runs.... for a while. After a random period of time (like half an hour) I eventually notice the qB icon is gone from the tray, and that's it. Happens on at least 2 Win10 1903 instances. Can't say anything about earlier versions coz I don't have any.

[theswagler]

I rolled back to v4.1.5 too. I tried v4.1.4, but it drops window down on close like v4.1.5. It's not worth my time to test more previous versions, so I'll stay with v4.1.5 until next release.

[sledgehammer999]

The problem most probably lies with the usage of openssl 1.1.x series.
I released v4.1.7 and it uses the 1.0.x series of openssl. This should fix all your crashes.

[bviktor]

Thanks, let's hope it's actually fixes now. SmartScreen doesn't like this version btw.

[theswagler]

openssl ? Yup, external libraries. I hope it fixes issues. I really like the bind to IP feature, and it downloads quicker than uTorrent on my sorry CenturyLink DSL service out in sticks.

[xavier2k6]

@sledgehammer999 just confirming two things.

1. no silent crashes with 4.1.7 reported in eventmanager
2. no crashes either with an alpha build of 4.2.0 [been using/testing that since I came across it in June] that glassez compiled in torrent rechecking thread. (that used openssl 1.1.1.c & qt 5.13)

quick question regarding 4.1.7 - does that address the low security issue in openssl (CVE-2019-1552)
https://www.openssl.org/news/secadv/20190730.txt

Note

OpenSSL 1.0.2 and 1.1.0 are currently only receiving security updates.
Support for 1.0.2 will end on 31st December 2019. Support for 1.1.0
will end on 11th September 2019. Users of these versions should
upgrade to OpenSSL 1.1.1.

[Piccirello]

The problem most probably lies with the usage of openssl 1.1.x series.

@sledgehammer999 could you add some more info on this and why you suspect openssl to be the cause?

[xavier2k6]

@Piccirello If you look through the comments - I had previously pointed out that at the time QT 5.12.x had not fully implemented support for OpenSSL 1.1.1 series......it became fully compliant in 5.12.4 & 5.13.

https://blog.qt.io/blog/2019/06/17/qt-5-12-4-released-support-openssl-1-1-1/

Also - I have confirmed that there's no crashes with a test build of 4.2.0 which uses Qt 5.13 & OpenSSL 1.1.1c

[a4h7]

4.1.7 has seemed to have crashed as well now

[xavier2k6]

4.1.7 has seemed to have crashed as well now

@christianwells11 can you give some more details....are you getting a silent crash (logged in event viewer) or an actual crash with debugging info?!

Did you also try:
#10581 (comment)

[theswagler]

I can confirm v4.1.7 is working great on Win10 2016 LTSB. No window movement at minimize, and no (2) popup dialogs informing crashing after closing,

[sledgehammer999]

To all of you who 1) had crashes with official v4.1.6, 2) then didn't have with the build I provided of 4.1.6 using openssl 1.0.2 and 3) don't have crashes with official v4.1.7

can you try the following build? It is 4.1.7 using the exact same lib versions as the official but openssl is 1.1.1c. Do you start having crashes?

Link: http://builds.shiki.hu/temp/qbittorrent_4.1.7_x64_for_issue_10581.7z

[a4h7]

Working so far.

[xxn1202]

I‘m using official v4.1.7,but it crashed several times, maybe too many torrents?

[xavier2k6]

@xxn1202 can you provide some more info please......silent crashes ie as in logged in event viewer or actual crashes......debug window showing with crash report?

[jjaaccoobb]

Experiencing the same with v4.1.7

Win 10 Pro 1903 / OS build 18362.295

After killing the unresponsive task then restarting and waiting 5 minutes or so, program begins responding. Note, I have many torrents partially complete which are very large (50+ gb) and around 20 other misc. Think it may be just scanning.

[xxn1202]

I'm so sorry that the crash happened several weeks ago, I could not find the crash report. If the crash happened again ,I will tell you in the first time. 在 2019-09-01 05:26:59，"xavier2k6" <notifications@github.com> 写道： @xxn1202 can you provide some more info please......silent crashes ie as in logged in event viewer or actual crashes......debug window showing with crash report? — You are receiving this because you were mentioned.

[Krumpet]

Can't upgrade to 4.1.8 on Win10 1903 OS Build 18362.356. I'm getting:

Windows protected your PC
Windows Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.
App: | qbittorrent_4.1.8_x64_setup (1).exe
-- | --
Publisher: | Unknown publisher

For both 64 and 32-bit installers.

[Trefle10]

Just a quick thing to check for everyone having issues just launching the app. make sure you run as Admin otherwise for me it looks like it want to open but just closes itself.

[FranciscoPombal]

Original issue report and most comments pertain to an issue that was already fixed, see
#10581 (comment) and #10581 (comment)

All others still experiencing crashes in the latest version please submit a new issue with stacktrace as they are most likely related to something else.
