Fusion 360 Won't Load

james_carson — Thu, 23 Apr 2026 10:26:32 GMT

I updated Fusion 360, and now it either gets to about 45% and crashes or loads the Fusion support window. I don't have the old install to try installing the older version. I've tried uninstalling and reinstalling the latest version, and repairing it through the support window, but nothing works.

When was it released? I updated this morning, and then the problems happened.

Downloaded and installed again, it opens with the Fusion Service Utility again after installing.

Is there a specific location I can download it from? I downloaded the free use version again and am getting the same problems.

That took me to the same download page I did this morning, so it's already been uninstalled and installed twice. Attached is the log file.

Hi @james_carson ,

Have you installed any Virtual machines on your machine or installing Fusion on a Virtual machine.

Also

Provide your OS version.

@james_carson

Can you please try this?

1. Make sure that Fusion installer is not running in task manager
2. Go to %localappdata%\Autodesk\ then DELETE the following folders – Webdeploy, Web Services, Identity services, Autodesk Fusion 360 ((IF you do not have any other Autodesk products installed, delete the Full Autodesk folder)
3. Delete the shortcut that is used to launch Fusion
4. Restart your machine
5. Do not use the same Fusion installer. Can you please download the installer again
6. Now install again

I did all this and still get the same results.

@dsouzasujay I'm running Windows 11 Pro version 25H2. Attached are the screenshots you asked for.

@james_carson IN the service utility can you click on gather system info and attach the Fusiondiagnostics.zip file that it generates?

Re: Fusion 360 Won't Load

james_carson — Sat, 25 Apr 2026 20:00:25 GMT

Where does it generate that file to?

Re: Fusion 360 Won't Load

james_carson — Sun, 26 Apr 2026 15:25:54 GMT

I can't find the Fusiondiagnostics.zip file

Re: Fusion 360 Won't Load

RajkumarIlanchelian — Sun, 26 Apr 2026 21:39:46 GMT

@james_carson The file should be in this location - C:\Users\(username)\Appdata\Local\Autodesk\Autodesk Fusion 360\

Re: Fusion 360 Won't Load

james_carson — Sun, 26 Apr 2026 23:34:49 GMT

it didn't create a zip file, but there was a folder there with that name, and I zipped that up.

Re: Fusion 360 Won't Load

james_carson — Mon, 27 Apr 2026 01:17:29 GMT

It doesn't help. I've done the uninstall/reinstall thing several times now, and the registry entry is already set to 1

@james_carson @Let me look at the logs some more. Can you try one quick test?

if you create a new admin user on that machine and install Fusion does that launch ?
