COM Surrogate Has Stopped Working Fix: Windows Vista

5 05 2007
Even since I stated using Windows Vista in early november 2006 (thats right, Microsoft Student Partners get their copy early) I have never faced any problem with it. It has never crashed, nor restarted. To the maximum extend, it has only freezed some programs for a few seconds to allocate memory for other critical programs. But recently a new problem popped up. Whenever I browse some folders, the “COM Surrogate Has Stopped Working” error pops up. It doesnt hinder with the perfomance or data loss, but I find it quite irritating. So does some of my friends.

The simplest and shortcut solution is as follows that worked for me:
1. Right click on Computer, and choose PropertiesRight click on Computer, and choose Properties
2. Click on Advanced System Settings, and then under Advanced, click Settings\
3. Select the “Data Execution Protection” tab, and then click “Turn on DEP for all programs and services except those I select”
4. Click on the Add button, and then browse to C:\Windows\System32\dllhost.exe as shown
5. Click Open, and then OK.
Your’e done!!! Now it should work fine for you in 99% of the cases.
But if the problem still persists, then this could be due to a software installed on your computer. DivX and Nero are a common cause, but there are others that cause the problem as well.

Possible Solutions
- If you are using DivX, you should be upgraded to the very latest version 6.5+)
- If you are using Nero, you can try upgrading to the latest version (7.7.5.1+)
- If you’ve upgraded Nero and Divx and still have the problem, you can try renaming the fileC:\Program Files\Common Files\Ahead\DSFilter\NeVideo.ax to NeVideo.ax.bak. You may also need to rename NeVideoHD.ax to NeVideoHD.bak. Caution: Nero Showtime will not work anymore
- The older ffdshow codec pack has been known to cause some problems. The ffdshow tryouts codec pack seems to work better. Might want to try using this one: http://ffdshow-tryout.sourceforge.net/

For those running AVANT Browser and who apply the DEP fix for this by adding dllhost.exe to the DEP listing!!!

This will cause Avant Browser, and possibly other browsers and programs to also Stop Working!

Workaround (Tested) – Add Avant Browser EXE to the same DEP list, and in the same manner as you added dllhost.exe, and it will work again. Same goes for any other programs that may stop working right after applying this COMM Surrogate fix.

Don’t have Nero. Don’t have Divx. Can’t make such changes to DEP in 64-bit Vista.

I appear to be screwed for the time being.

i think the com is the problem with my video editing software
every time i go to save and finish the movie into a playable format *avi .exc
the program freezes then closes
after this “fix” i cant even open up a program that has to do with video, pictures, or audio. any one else have this problem
- PJ :-)
p.s. – going through files is fine though

I’ve tried the DEP settings, the Nero update, the Divx update & i’ve renamed both the nevideo.ax & nevideohd.ax with the .bak and still nothing

the first shortcut solved the problem of my video programs crashing. but i still get the error when viewing thumbnails in explorer and in wmp.

Ok, looks like i got it working. I just uninstalled all my divx programs. then reinstalled the current version of ffdshow. I think its in version 6.1 now so if you dont have the latest you might want to give it a try. http://www.afterdawn.com/software/video_software/codecs_and_filters/ffdshow.cfm

I still have my settings to turn off DEP for certain programs like outlined above though. But my computer seems to be back to normal.

This fix doesn’t work on 64 bit Vista…unfortunately.Anyone has an alternative solution for this f…king COM Surrogate error?

30 04 2011
Ron

I”m not sure when your question was put here but I was wondering if you have heard of a fix for the Vista 64 bit. I’ve been looking everywhere and it seems like the the fixes all still only for Vista 32 bit???

Installing the Vista Codec Bundle was the key. Thanks!

Thanks a lot man.
I really got rid of the bloody thing ‘COM SUROGATE HAS STOPPED WORKING’.
Basically I removed softwares on after the other nero , vlc,divx.
restored the system .. no result..
Then I removed the klite kodec .
then onwards the error message did not appear..
Thanks a lot again..

And one more thing is I have also checked the ‘Turn on DEP for all programs and services except those I select’ and added hostdll.

This didn’t work for me, and on top of that, it’s broken my movie maker. I’m downloading SP1 right now and installing it to see if maybe that helps fix the problem.

Will let you know the results.

17 05 2008
Lydia

Even installing SP1 didn’t fix it. Looks like my WMM and whatever else are permanently broken. Just further testimony to: Don’t Buy Vista.

The original solution at the top of the page worked perfectly. However now my guest account has stopped working completely. Nothing loads up when I log into the guest account. I get allot of error messages which pop up, and all the shortcuts on my desktop are blank. The error messages are all the same. They say the “insert program name” can not open. Then Vista attempts to ask me to choose a program to open the processes which effectively make my guest account not turn on. Please do not tell me I have to go back in and manually add ALL of those programs to that list as the fix above mentions for the comm surrogate error?

These are all of the windows which “Instantly” pop up as I attempt to load the guest account.

1. MSASCUI.exe
2. Nerocheck.exe
3. Rthdvcpl.exe
4. Zclient.exe
5. Language.exe
6. Ufseagnt.exe
7. Updreg.exe
8. Winampa.exe
9. Rundll.exe
10. Khalmnpr.exe
11. Volpanlu.exe
12. Reader_Sl.exe
13. Jusched.exe
14. CTXFhelp.exe
15. Logitech Setpoint.exe
16. Sidebar.exe

I have got one suggestion for your site. It seems like there are a number of cascading stylesheet problems when opening a selection of webpages in google chrome and opera. It is running alright in internet explorer. Possibly you can double check this.

The divx codecs is the problem it’s not read by vista

1. Just uninstall divx
2. uninstall and all codecs.

t===he divx codec in the divx package corrupts the codecs and vista can’t read it after corrupting it==

3. reinstall codecs but not the one from divx.

!!!!!but don’t use an divx codecs!!!!!

just install the divx PLAYER Only!
====Don’t install the divx codec when installing divx player ==

NO divx codec the problem is the divx codec not compatible or conflicting with windows vista. i wouldnt recommend going to system as changing settings it is dangerous
