The VideoLAN Forums

Hi everyone,

I downloaded vlc 1.1 and still have application crash when launching. the same pb I posted on viewtopic.php?f=34&t=76833
Can this be related to libQt4plugin.dll ?
Can this be related to font pb (I am running japanese Vista with french language installed)?
It's a pity because I was really looking forward new features (sync) of this version...

Thanks for any help !

You tried to remove %appdata%\vlc folder?

yes I did... and problem was not solve...

I also tried to replace libQt4_plugin.dll in 1.1 with a previous version of vlc (1.0.6) and vlc didn't start.

I uninstalled vlc completely, deleted all files I could find after proper unsinstall with option "delete cache" activated. Then reinstall : same problem.

as Blu28 found out on 1.1RC version forum, if I launch directly a video using vlc, application start playing the file with the same error message above. Clicking on the message cause the app to crash.

As I explained on this forum, windows log shows (in french sorry):
Application défaillante vlc.exe, version 1.2.0.99, horodatage 0x4bfda104, module défaillant libqt4_plugin.dll, version 0.0.0.0, horodatage 0x4bfda10f, code d’exception 0x40000015, décalage d’erreur 0x000037c2, ID du processus 0x1488, heure de début de l’application 0x01cafd7d768fe937.

I wonder if it can be a pb close to : http://www.mail-archive.com/qt4-preview ... 01052.html ?

thanks for your help!

You are using 1.2-git, don't you?

no..? I installed the git version for a test a while ago and desinstalled it completely ... I download 1.1 version from http://www.videolan.org/ home page...
I retried to desinstall / resinstall this morning...nothing changed...

"Application défaillante vlc.exe, version 1.2.0.99, horodatage 0x4bfda104, module défaillant libqt4_plugin.dll,"
This is 1.2.0-git

Please delete manually the complete VideoLAN/vlc install folder

thanks for your answer j-b !
This sounded indeed obvious... but I didn't saw it... thanks a lot.

What I tried :
1 - I uninstalled VLC normally and delete folder videolan/vlc folder
1 - I found out that another version of VLC was installed through a french program called AdslTv... I uninstalled everything...
2 - I deleted c:\windows\prefetch\ files related to VLC...
3 - I reinstalled VLC 1.1

but then : same pb with right version :
Application défaillante vlc.exe, version 1.1.0.0, horodatage 0x4c1eb4b8, module défaillant libqt4_plugin.dll, version 0.0.0.0, horodatage 0x4c1eb4c0, code d’exception 0x40000015, décalage d’erreur 0x000038df, ID du processus 0x1074, heure de début de l’application 0x01cb151095308eb2.

??? I got crazy ? what's going on ?... seems that I'm the only one to have this pb ?

You have some custom Windows theme engine installed?

Delete %appdata%/vlc too

when unsintalling vlc, %appdata% doesn't contains a vlc folder anymore...I guess the file is correctly deleted by the uninstaller...

I have no special windows theme installed.. I was using a vista theme modified... but.I already tried to come back to default vista theme and even xp theme... and it didn't solve the pb.
But I have a "japanese version" of windows vista where French language pack was installed...I have sometimes pb with fonts who appears in japanese letter instead of roman... that can be the issue ?

It could but it should crash. You have drawing tablet attached to computer?

no, this is a sony laptop with a touchpad... and nothing connected...
and previous versions of vlc worked perfectly...
Is there a light way to debug / check libqt4 dll file ? or vlc ?
thanks for your answers anyway ...

What did and tried :

1. VLC 1.1 installed on top of VLC 1.05
crash on starting
2. uninstalled VLC normally and delete folder videolan/vlc folder
3. deleted the VLC folder and the %appdata%\\vlc folder
4. run CCleaner
5. installed VLC 1.1
crash on staring
6. repeated points 2, 3 and 4
7. re-installed VLC 1.05
Working nice like before!

(Windows 7, 64 bit, desktop)

so you came back to 1.0.5 ?

Yes, indeed.
VLC 1.05 is back on my system.

Is there a light way to debug / check libqt4 dll file ? or vlc ?

Yes, run VLC debug builds under gdb.

ok, but my problem concerns 1.1... I can use 1.0.5 as well...
