Avast 5.1 in conflict with Cyberlink PowerDVD

Avast Free Antivirus / Premium Security
1

I recently upgraded from Avast Free 4.8 to 5.1, and suddenly my PowerDVD application does not work. I get an error message saying that the file CLHelper.exe has crashed, and I’m unable to play DVDs and blu rays.

When I uninstall Avast completely, PowerDVD works again. Can anyone guide me on what to do?

I have the exact same problem, and made a thread about it here. Doesn’t look like there’s anything to do until they fix it (I hope they do.) I don’t know if it would be possible to roll back the program update somehow, at least for now.

What is your OS? Are you using the latest (.889) version of Avast!? What firewall are you using?
Couple things to try to get more conflict information for the developers:

  1. There have been a few reported residual issues with the Behavior Shield. Go to Programs and Features, select Avast, uncheck behavior shield to remove it temporarily and see if that fixes the problem.
  2. Do an uninstall of Avast! in safe mode with the Avast! uninstall utility. Then a custom reinstall using only the file shield. If things work, try adding back the Behavior Shield, Network Shield, etc. from Programs and Features.

I’m on Windows XP SP3 32-bit, Avast Free 5.1.889, and I get this error. I tried your suggestion and uninstalled the Behavior Shield and after that PowerDVD worked fine, so that’s definitely the problem. Will probably keep it like this for now, better than nothing.

Thank you. Glad it helped for now. The developers may contact you directly for dumps or other information that will help them fix the problem. With 140M registered users there are sure a lot of different configurations. :slight_smile:

I also have the same problem. On starting PowerDVD 8, clhelper.exe crashes and the playing of blu rays or DVD is not possible. I am surprised that there is so little on the web about this problem. It looks potentially significant to me! I am running Windows XP SP2.

Have you tried the suggestions in Reply #2?

Thank you for the prompt reply. Yes I have tried the suggestion in Reply #2. PowerDVD 8 runs correctly if I choose not to install the Behaviour Shield. As stated previously, I suspect that this may be a significant problem. Since clhelper.exe just crashes, many users may not be aware that Avast is at fault.

Thread has been reported to support as an issue.

Thanks. I always do the same when my (or others’) knowledge can’t solve a problem.

Thanks for the quick replies! I tried the steps in Reply 2, and still the same results. I’m running the latest update of Avast, and have Windows XP 32bit SP3.

Try a removal of avast! using the uninstall tool from safe mode, then a clean install without Behavior Shield. I think the others with this problem were doing upgrades from 5.0 versions.

Response from Avast! Sypport: "Till we will very very soon a new version of avast to fix this issue, please reinstall avast with the following version: 677 "

Where do I get version 677 from? When do you anticipate releasing a fix? Thanks

One other route to try: I’m having no problems with 5.1.889 and Power DVD 7. A few months ago I had to replace my DVD drive, and the new one came bundled with an installation CD for v. 8, but that turned out to be an OEM version which lacked some components (I forget what) essential to viewing commercial DVD videos. So I restored my HD to the previous day, to get ver. 7 back, and it was fine again.

So see if you can find somewhere (Cyberlink, maybe?) a copy of Power DVD 7 and try that. To the best of my memory, the only significant change in v. 8 vs 7 was the ability to add other skins to the default one.

This link is for the Free version. What about Internet Security ? It also conflicts with PDVD9 Ultra.

Update, since I now remember … what was missing from that OEM version of PDVD was that it wasn’t capable of handling Dolby, which I would have thought is more or less universal these days, even on remastered antique films. So no audio at all.

Hello,
Like everyone else here, I also have the problem with CLhelper.exe crashing when I start PowerDVD 7 OEM and have been patiently waiting for the promised upgrade that supposedly fixes the problem. This morning version 6.0.1000 and definitions 110226-1 came out and I upgraded, but the CLhelper problem is still occurring. Was this supposed to be the version with the fix in it? If it was, then it needs to be looked at again.

Thanks

Same here, the update to 6.0.1000 hasn’t fixed the issue. I still have to install Avast without the Behavior Shield.
