How to uninstall DivxFilter because there is no uninstaller
 

I can open Divx Movies normally but i could not find a uninstaller at add/remove programs.

Also i checked in BSplayer when running a divx (avi) file, this computer is not mine (my uncle's) and i do not know how this filter installed.

Also i could not find a codec pack information in add/remove programs.

I send a informational screenshot of the filter shown in Bsplayer.

Can't you find it under [Start] > [Programms] > etc. ?
(Shows 2 remove options: bundle and codec)

(picture concerns 5.2.1. version of codec)

Depending on version of BS.Player you can use its filtermanagement:
(rightclick > Options > Preferences > Filter management > [Filter manager] > Video decompressors
to unregister filter.

Otherwise through [Start] > [Run] > and then:
%windir%\system32\regsvr32/u [full path to .ax-file]\[name of .ax-file]
Which means in your case:
C:\Windows\system32\regsvr32/u C:\Windows\System32\Divxdec.ax

For Win9x systems:
%windir%\system\regsvr32/u [full path to .ax-file]\[name of .ax-file]

:wink:
Further there are also several possibilities offered by Windows (the following indications are for XP):
Either rightclick on "My computer" > Properties > [Hardware] > ....
or go from System configuration screen > [System] > [Hardware] > ....
... then: click on first option > drivers for sound, video and games > video codecs > [Properties]

(Note "labels" are translated from a Dutch OS, so they may differ)
Yet another possibility is:
System configuration screen: > Sounds and audioappliances > Hardware > Videocodecs > [Properties] (2x) then you can select codec and remove it.

There is no start-up item indeed in c:\program files\

So, you regsvr32 tip is the unique chance it seems.

But does unregistering a filter mean to remove it completely or should i delete some .ax files manually?

Thanks.

I just edited my post adding other options; please check.
Just unregistering doesn't automatically delete/remove the files.
I think most probably the Windows-offered-options to "remove" indeed do.
(Didn't really try that if you don't mind :wink: )
