So far so good. Been over a day now with no more errors. I took the .dll files that kept getting posted as bad image errors and put them in the excluded Mcafee scan folder. Reloaded the latest version of Sonar artist and it seems to have worked.

Windows Version: 10 Home 1709
Software Issue: Corsair Utility Engine
DLL Affected: Various in the CUE folder depending on me re-installing, 0 byte dll's
Error Message: Bad image
When did the message show: On windows startup, but only occurred after the Windows 1709 update
Antivirus: McAfee
 
only reason I posted was because its not just Sonar thats having this problem over the last few weeks. Members of Corsair are reporting it to. So its either Windows update or Mcafee

Hello,
 
Lately when I try to use Sonar on my Windows 10 laptop, I sometimes get an error message indicating that DSDConvert.dll (and sometimes a couple of other DLLs) are corrupt. When I examine these DLLs in file explorer I find that they have a size of zero bytes. At that point the only recourse is to reinstall Sonar.
 
This happens sporadically; sometimes I will get several days without seeing the problem, and sometimes it happens every other time I start Sonar. The obvious question is "What's changed in the environment," but the only answer I have is "Nothing to the best of my knowledge" (though we live in an era of automatically-updating software so who knows what has happened behind the scenes).
 
I use a Focusrite Scarlett 2i4 sound module connected via USB, in case that's relevant. Any ideas as to what's happening would be greatly appreciated!
 
Thanks!

Yes, that's very helpful! I had begun to suspect McAfee AV when Process Monitor showed it accessing the affected DLLs as I started Sonar. I could never catch it in the act of truncating the files, though. I've removed McAfee and turned on Windows Defender. So far so good.
 
Thanks very much for your help!

You're welcome. I'm sure Sonar will work as intended with Windows Defender enabled.

I don't have McAfee but encountered this problem with Sony Vegas and Windows 10.
 
Also at the moment. I can't install any updates. I get the "Your device is at risk because it’s out of date and missing important security and quality updates. Let’s get you back on track so Windows can run more securely. Select this button to get going." Clicking the button just brings up the same warning.

I am too experiencing the same issues on my daw and my new laptop with a very recent install-both using macaffe- security suite.
I just excluded the dll's from being scanned and have also made a sonar backup folder.
I will post anything I find

@ whoever turned me on to this thread, thank you. while reading through the posts i see a couple common things. my biggest problem is, i don't know how a computer works so when you guys start talking about DLL's and things like that i'm lost. however, one thing i noticed is there could be a problem with Mcafee. i remember when i first started using a DAW (cakewalk guitar pro running millennium) i had to manually (ctl-alt-del) shut down background programs and never, ever run AV because GTP would crash. however, by habit, i always disable AV while running Sonar.
that being said, i still have no idea how to fix this and it's becoming quite annoying.

Version of Windows - ( 1703 1709 etc)  IMPORTANT 
Version of Sonar  probably doesn't matter. 
What the message said  
When does it happen
And yes are you using McAfee
(Better question)
What antivirus software are you using?

This could be affecting other A/V software, not just McAfee.

2 whole days now-no trouble
I added all the dll's from the sonar plat folder to the "excluded files in McAffe. seems to be the culprit on my 2 machines
thanks for all the support on this thread

Keith, you guys should be following this issue, It does seem at this point it is McAffe 90% of the cases. 
 
It might be pertinent to make a statement to Sonar users if this can be verified officially. 
 
 

Yeah, I started having this problem this weekend.  My system's nothing special...I'm on W10 1709.  I didn't have this problem before I was updated to 1709, (which was a couple weeks back).  In addition to DSDConvert.dll being affected, CWVideoEngine.dll was affected once as well.
 
An alternate method to recover would be to roll back a version, then update again.  This will help out folks who hadn't backed up the .dll(s) that got affected.  This recovery took me about 4 minutes to complete.

Been using SONAR for 5 hours closed it down for lunch with no issues. Tried to start it again and immediately got C:\Program Files\Cakewalk\SONAR Platinum\CJLibrary.dll is either not designed to run on Windows or it contains an error? 

without any windows or sonar update during lunch?

Just checked CJLibrary.dll it was updated yesterday when I tried to restart SONAR (When it failed) and is now showing 0KB in size
