Hello!

I keep getting this error message while running Vmix (see screen capture)

"Attempted to read or write to protected memory.... Unhanded"

Running windows 10 64 bit
Gigabyte brand laptop. Intel i7 2.60 GHZ
Installed memory 16 GB (Crucial brand)

Vmix 19.0.0.54

It usually shows up in about a half hour of running Vmix.
As tests I would just let vmix run and not do anything -- and then it pops up. sometimes in about 30 min. Sometimes takes a little longer. But sooner or later it pops up.

I assume the message is being generated by Vmix.

I did some hours long memory tests and got no errors. It was a very deep memory test. So it appears my memory is good.

BTW even if I am not streaming I get this message.

So I am wondering if something else is triggering this message???

I see that I can push a button to "Send Error Report". I assume that error report is going to you people at Vmix.

It would be great if I could view that same error report -- in case it would help me trouble shoot this issue.

Thanks!

I have seen this on AMD graphics cards.

Better to go to Nvidia GeForce Experience to check for updates. Wouldn't trust Windows for that. Heck, Windows will try to update in the middle of a broadcast!

Hmmmm


Here's the install screen I see in the Geforce thingie. Two of the items are already checkmarked by default.

The Graphics driver is unchecked even though it says I have an older version installed. It is also possible that my specific card does not actually support the update....

New: 384.76
Current Old Graphics Driver: Version 376.54

The panel won't let me check the new version of the Graphics driver. Not sure why. Maybe it wants me to install the 2 other items first.

However, my question is for Vmix (I'm not a game player) do I even need the "3D Version driver" or the PhyxSystem Software.

I want to be conservative regarding what I install in relation to my drivers -- and only add what Vmix wants. (To keep future troubleshooting simple :)

Please see attachment. I'm holding off installing anything from the Gforce thingie until I hear opinions here.

Still running Vmix with no errors with just the Intel video driver updated.

Thanks!

I think it just means that the new driver will be installed anyway and you can't deselect it. Give it a go...

Interesting -- it says the Intel HD Graphics 530

There is also "Default" which is not selected.

Nowhere do I see the Geoforce Nvida driver as an option in the dropdown.

Interesting!

Would not Nvida be a better choice, since it is installed.

HEre's a screen shot of my device manager, so the GTX is definitely installed.

Rowby

You were correct. I did the install and the updated Nvidia driver was installed.

So now I have the latest Nvida driver.

Will see now if Vmix recognizes that driver. Instead of the Intel driver. WIll do a reboot and see what happens.


Rebooted Windows 10

Have the updated Nvida driver

22.21.13.8476
This device is working properly.


Vmix is still reporting that it is using the "Intel Driver". Again the only other option is "Default". So sticking with Intel driver until the Vmix Forum tells me otherwise.

Letting Vmix run and see if any errors pop up.

WIll report back!

Thanks again everyone. Amazing forum support.

Actually I never use the "experience". It installs a bunch of junk for gamers you don't need. I go to www.nVidia.com and download the drivers. I then select custom install and only load drivers - not the Experience.

my 2 cents. :-)

Also, if you do the Creators Update you will have control over when Windows Updates happen - finally!


Steve

Here are my Nvida settings.

Good idea.

Went into setup and did the error report thingie. I'll report back here when I have some updated info.

Thanks!
