BleepingComputer.com: PowerDVD 10 Ultra crashing

My PowerDVD 10 doesn't work anymore and even re-installing the application didn't do anything. It's just giving me this message;

This is a legitimate version that I bought and paid for from Cyberlink's site. Why did it suddenly stop working on me?

One thing I forgot to mention was that it was working fine for several weeks previously and the only change I did to the system before PowerDVD stopped working was install an Auzentech HD HomeTheater sound card.

Hi Phoenix.

The problem here is an audio driver conflict. When you added the Auzentech HD card, did you disable your onboard audio? The RTLCPAPI.dll indicates the presence of a Realtek audio processor. These can be found in many mainboards, as well as AMD ATI Radeon video cards (HD 2000 - 5000 series). To test if this is the solution, open Device Manager (Right click on Computer, select Manage, then click on Device Manager) and expand the 'Sound, Video and Game Controllers' section. Right click on any/all Realtek or ATI High Definition Audio device entries present, and select 'Disable'. Once you've disabled them all, Cyberlink PowerDVD 10 should start. Make sure you install the latest patches for PDVD if necessary.

If this solves the problem, you can enter your computers BIOS and disabled the onboard audio from there. You can't do that for the ATI HD audio, just have to do it in device manager.

Hope that helps,

Many thanks caveman-jim,
my circumstance was exactly the same as phoenix vii, and your advice fixed my problem.

Thank you very much caveman-jim!! it was a very helpful solution for me as well

Many thanks, Caveman-Jim! I had the same problem with PowerDVD 9 (Windows 7 Ultimate, 64-Bit), and your fix worked perfectly. Maybe this is common knowledge, but it seems like it should be referenced in the installation details that come with new devices; even my PC manufacturer (Dell) only mentions changing the audio controller in System Setup, not in Device Manager. For me, PowerDVD has continued to be problematic whenever I make any changes that involve video and audio devices or software; my VLC Media Player and ArcSoft TotalMedia Theater have both remained rock-solid through any system changes I have made, whereas PowerDVD 9 is very touchy as to which new codecs may interfere with full operation. Okay, now that I have put everyone to sleep with my video rant, I will close with a final 'thank you' to Caveman-Jim! Best regards, Dana
