Re: Error during preview
Broke it again
Removing Avast, even without a reboot, restores my webcam display. I didn't test it with my various frame grabbers, but I willing to believe that Avast was the culprit.

Re: Error during preview
Thanks for trying that. At least the error can be reproduced consistently on your hardware.
There are 4 variants of Avast - Premier, Internet Security, Pro, Free - which are you using?
There are also articles on the web about how to configure Avast to exclude programs from the various shields. It might be worth asking Avast support, particularly if internal cameras are broken since 28th April. This might get fixed by them in due course.
Let us wait and see what happens with the other posters with this issue.

Re: Error during preview
I was running the free version of Avast and did try to take a stab at excluding the SharpCap 3.0 directory. It didn't work.
Re: Error during preview
Uninstalling my free Version of Avast fixed my issue.
I then used Windows Defender and the issue returned.
For now, I have to turn off (disable) the live protection mode on Windows Defender to use my webcam with SharpCap and most other applications.
But at least I can use it. That is when and if the skies ever clear in Mid-Michigan
Thanks again everyone for your help

That is another Avast PC with the symptoms.
Can you open a command prompt and post the output of the ver command please, so I can see which version of Windows you are using.

Re: Error during preview
Dave,
there is another user with the same problem who also used Avast here - http://www.astronomyshed.co.uk/forum/vi ... 5&p=196036. The evidence is pretty damning....
cheers,
Robin

Have a look at the Avast removal tool https://www.avast.com/uninstall-utility. The Avast uninstall via Windows might not clean up completely. This might have something to do with why Windows Defender is playing up as well.
I tried to reproduce the problem by installing Avast Free on a Windows 10 Creators build but everything worked properly. I cannot reproduce the conditions of 29th April now with Avast. Something that was broken might now have been fixed.
Have you considered a system restore back to prior to 29th April?

Re: Error during preview
Dave, Robin, Thanks again for all the attention on this issue, especially now that it seems to be solved.
Output from VER:

C:\Users\Ray>ver
Microsoft Windows [Version 10.0.14393]
Dave, I will look at the removal tool and see if that makes a difference. I did use revo uninstaller thinking that would clean everything up but perhaps not. If the uninstall tool you recommended does not work, I will investigate another AV program.

Re: Error during preview
Dave, Just an update. Your suggestion to run the AVAST uninstall tool worked a charm!
Every webcam program works now with Windows Defender live protection enabled.
Avast is very tenacious to escape the revo uninstall and removal program!
Thanks again!

The output from ver tells me you are running a fully patched Window 10 (prior to the Creators update).
You might want to download Avast and install it again - at least you know how to fix it if the problem occurs again. All AV products have 'special' clean-up program.
I spent 30 years supporting computer operating systems - hence the first question I asked was more than lucky. AV products have caused me more pain than the stuff they are protecting against.
On my image capture laptop, I don't run any AV software other than Windows Defender. This is not a risk as I never browse the internet with this particular laptop.
