All versions freeze on startup

[GLDevco]

I've got a weird one - I have 2027 and 2026 on my computer, and even 2025.  When I start AutoCAD, either from the shortcut, opening a file from Explorer, or even from the NVIDIA app, the program freezes after a few seconds of opening.  I have reinstalled these versions, ensured I am up to date on the OS, and performed a clean installation on my NVIDIA card. (RTX 3080).  I also reset everything in AutoCADD to the default.  When I did the clan install, AutoCAD worked for one session, then gave up on me.  Another weird detail: AutoCAD Maps 2026 works!

I'm attaching this weird detail as well. The program freezes as the Autodesk Assistant dialogue tries to fade out; see the attached picture.  I do have another machine that I just put 2027 on, and it seems to operate normally.  It doesn't have the same NVIDIA card, but it does have the exact same driver.  Revit and other Autodesk products are working just fine.

Any thoughts on what else I should try?

Has this just occured today? I've got the same problem. I'm running out of ideas to fix this. 

[GLDevco]

It started yesterday for me.  I don't think it's the NVIDIA driver because that was the first thing that I updated when it started happening.

Gone are the days when the Forum is the first place to go after you try everything in house.  Autodesk's Generative AI support bot saved the day on this one, there is a problem with a Windows Update:

Uninstall the Windows update
1. Open Settings (press Windows key + I).
2. Go to Windows Update → Update history.
3. Scroll down and click Uninstall updates.
4. In the list, find update KB5083769 (or the most recent update you suspect). Select it and click Uninstall.
5. Follow any prompts to complete the uninstall.

I uninstalled this exact update, and now AutoCAD works again.

Good deal. Thanks. That update was from April 14th, or at least that's what the Windows Update History told me. I had no problem with the freezing, and neither did my workmate, until today. So I had ruled it out. But I uninstalled it and I'm up and working. Thanks again!

If you uninstall every program besides autocad from autodesk it will work.

The problem is on side app from autocad

[kdegraauw]

this does NOT work if you cannot delete that update. My computer will not allow me to for whatever reason, no matter what I try. It is embarrassing that Autodesk is jumping on this as a "fixed solution" when it doesn't totally work.

Hello everyone. I had the same issue with Map3d 2026. No version worked (2025 or 2027). I removed the update and everything works fine. 

Windows keeps trying to install the update, so i guess Autodesk will find a solution to this conflict.

Thanks everyone.

Well, let's hope this gets figured out because I don't like the idea of keeping a security update uninstalled.  But to confirm, after installing Update KB5083769, Autocad works once again.  Thanks for you help!

[bruce2]

That worked. Thanks for identifying the issue. This is not good though as security updates are necessary for a safe computer. Hopefully Autodesk fixes this issue tomorrow!

Has anyone who can't uninstall update KB5083769 found a solution?

[peter_plpm]

This fix worked for me as you will likely not be able to uninstall the update from Settings - Windows Update etc..
In my case I queried Google AI via Google Chrome - "how to delete a windows security update KB 5083769
Answer "Method 2: Via Command Prompt (Advanced)
Open Search and type cmd.
Right-click Command Prompt and select Run as administrator. (if you do not have administrative rights then you will not be able to follow this fix)
Type the following command and press Enter:
wusa /uninstall /kb:5083769.
Restart your computer to apply changes". 
ADDITIONALLY - Consider pausing updates for a couple of weeks until MS get their act together as auto update will try and reinstall it almost immediately
Obviously you do all this at your own risk.

Interestingly, when Update KB5083769 reinstalled yesterday, my AutoCAD now works fine.  The version of AutoCAD I am using is U.119.0.0 AutoCAD 2024.1 if that makes a difference. 

[fvossHMDGV]

Well, nevermind.  It took 6 days, but now the same thing is happening again.  KB5083769 is the latest update, installed 4/21/26.  Going to remove it again right now.

[CoryMillard]

you can force it via Command Prompt.

1. Open Command Prompt or PowerShell as Administrator.
2. Type the following command and hit Enter:
   wusa /uninstall /kb:5083769
3. Follow the prompts to restart your computer.

After hours of trying every fix and not being able to uninstall the windows update I was able to reach an agent who told me the following which worked for me and doesn't require uninstalling security updates. Hope It saves someone time and frustration.

As a workaround, rename the AdDownloaderCore.dll file in the C:\Program Files\Autodesk\AutoCAD 202x folder.

[kdegraauw]

Hey could you please clarify what you renamed the file to make this work? And no need to delete this file, only rename it and the program recognizes things?

[kdegraauw]

Since this was a security update, this is not always successful either. I had to perform a complete reinstall of windows to get around this even after a windows disk image ralepaircand a windows image repair were both unsuccessful.

[kdegraauw]

Has Autodesk stepped up yet with a patch? Or is this just supposed to be the fix? I'd really like to " un pause" my security updates due to a software conflict problem. Seems like Autodesk and Microsoft need to chat and ASAP!

[austinmrTW5TT]

Just need to rename it to anything else, I went with renamedfile.dll
