Fusion login not launching browser.

[ROGsolutions2022]

Gidday all!

I have recently run into an error with Fusion 360,

The splash screen shows the login button, and when clicked this used to open the default browser and take me to an Autodesk login page, I would be able to login and then head to the desktop version and get started.

Now, unfortunately, it doesn't seem to launch the browser. So far I have tried:

1. Following the steps here notably, the Fusion Service Utility will not launch, and I am unable to locate debugger keys in the REGEDIT address provided.
2. Uninstalling, restarting and reinstalling Fusion.
3. Installing the Desktop Connector, the Desktop Connector crashes on startup also.
4. Signing in online (this works fine, however does not allow me to access Fusion 360)

Any further tips and tricks would be greatly appreciated!

Hello and welcome.  Are you able to see the browser in your Taskbar as if it did open someplace?  Could it be opening off screen?  If so, maybe try the steps detailed HERE to move it back onto your main screen.  Good luck!

@ROGsolutions2022 What is your default browser? If you switch it to another browser , does it work? 

[ROGsolutions2022]

Negative, the Browser was not initiated by Fusion, I have only one screen,
so fairly sure it couldn't appear off the screen...

Thank you for the link, I am currently on Mobile, but I will try this as
soon as I can!

Default browser is Firefox,

I changed the system default to Microsoft Edge, restarted Windows and no
change, still cannot log in.

Thank you,
Rog

 I should add, this is the message in the command line interface that is left behind after the desktop connector crashes:

@ROGsolutions2022 Can you go to the below location and collect that log file and attached here? 

• Windows OS: %localappdata%\Autodesk\Identity Services\Log\IdServices.log

Hello again,

Thank you kindly,

Attached is the log file, please advise where I should be looking for the
next clue in solving this!

Thank you again,

I am having the exact same issue currently as what ROGsolutions2022 explained, it happened over the past few days. i have access to 2 other computers and i am able to sign in on those and all works fine. those computer unfortunately aren't powerful enough to reliably run fusion. the only thing i can think may be happening in my situation is that i recently started a new subscription to Norton 360. i have tried to ensure that any Autodesk programs are fully allowed but i may be missing something. i have also done many of the steps outlined in other posts about sign in issues to no avail.

one other key issue i am experiencing is that i cannot get to the Fusion Service Utility, when i click on modify to open it my cursor turns to the loading circle then the Fusion Service Utility closes after a couple of seconds without giving me the opportunity to click anything. (video attached to show this)

[ROGsolutions2022]

That definitely sounds identical to my problem! Have you recently updated
Windows/anything else?

When you use the desktop connector, does it immediately crash?

It is probably worth uploading the log file, see the replies to this post
for where to find it. You need to press start + R at the same time and
enter %appdata% to get to the right folder.

Hopefully we'll both find an answer soon!

Cheers,
Rog

My apologies mate, seems the log file didn't actually attach.

Consider this attempt number 2! 

Thank you,

Rog

@Colenathan1991 @vegaande @ROGsolutions2022 Can all of you right click on the Fusion launch short cut and launch with launch as admin and see if that goes through? From the logs it looks like there is access error happening for the sign on. 

[Colenathan1991]

ive tried that, no change.

[ROGsolutions2022]

I am not sure what this is mate, but I think the link is broken, at least for me it is.

[ROGsolutions2022]

I have had a quick look through the logs, albeit on mobile, 

2025-04-22T19:53:03.068Z [AdpSDKUtil:20232, 4424] [IdSDKPlugin ERROR] Exception in SSOServerProcess::Start: Access is denied.

This is of interest, seems the SSO had a fault on startup. Is there a program that I'd need to run in administrator mode? I am fairly certain I have tried that, at least with the desktop connector. 

Any further tips appreciated! 

Cheers!

[ROGsolutions2022]

I have also tried that, no change, 

Attached is the updated log file,

I can see it tried to log in lots, but was denied access to SSOServerProcess. Not sure if there is any method to add that to an "always run in admin mode" list? 

I am using the admin account for this PC.

Cheers again!

It's exactly the SSO access that is blocking this workflow. Next step is this:

1. Go to C:\ProgramData\Autodesk
2. Right click on that Autodesk folder > go to properties > Security > Advanced
3. Ensure that users have full read/write

Let me know if that helped.
