Hi Seth, because I come on the forum almost everyday and read most every post I have seen this same issue a number of times. Each time it would seem to be a different dll that has been corupted. It would be interesting to see what all of these have in common. I was even thinking of starting a thread and ask how many people have seen that  dialog. 
 
 
I always get "Overloud.dll"  
My system has been W10 for a long time. I don't always run updates as I keep the machine offline. But back in Sept I updated everything, W10 and Sonar as well as a few plug in managers like iLock. 
 
I updated W10 first thinking this would be the best sequence. 
So when I was installing Splat update the last box I got was the issue with Overloud.dll and so I chose skip and carried on.  Sonar ran just fine and I don't use the overloud plug in is so all is good.
 
 
I think there is a new Sonar update now since then so I will try and run that tonight and see what evolves. 
I will make sure the Overloud.dll is OK as I think I can copy it from my W7 Laptop. And there is another clue, I updated my W7 laptop the same time I had no issues.  

I have a lenevo think pad with windows 10 and intel graphics and mcafee antivirus. Ive had Sonar Artist for over a year now with no problems until October 14th. The same day as several windows updates. In order to run Sonar I have to reinstall to a previous update but on next try it wiped out the same usual .dll’s and bad image errors happen again.

I have also uninstalled the updates with no lock. It’s very frustrating as I am not computer savy . I have read s few fixes about reinstallation but they do not work. I have performed scans etc.

It's not anti virus Chuck I don't have AV and I have this issue as well.

 
I've learned through the years that when trying to problem solve... saying "Its not" is the greatest fail of all.
 
For example:

Weve been seeing this problem for how long now ?
But he is just seeing it since last week ?
 
There are many contributing factors here that could be the potential problem.
We cant reject anyone's opinion if we want to figure out what is going on.
That includes yours, mine or anyone else's.
 
I might be getting tunnel vision thinking it is an Anti virus problem, no doubt. I will admit it. I have thought that since day one.
More than one user has mentioned they are using MacAfee (which lets face it, is right up there with Norton AV for being one of the worst).
but you have that same tunnel vision thinking its windows 10. Don't let our own visions stop us from solving the issue.
 
for all we know it could be Command center

I wound up doing a clean install of artist and it seems to be working fine for several tries but now back to the same bad image error.
 

I USE SONAR PLATINUM I GET cwvideoengine.dll  PROBLEM IT WONT OPEN UP EVEN AFTER HOURS OF BEONG UP RECORDING AND BEING USED----THEN IT WONT OPEN UP--- ON A FLASH DRIVE I HAVE FROM OTHER COMPUTER THE DLL'S THAT DONT WORK-- BUT I STILL RUN INTO THE PROBLEM 

Do you have McAfee?
