Fusion fails (or slow) to open (not responding) on start up

[jmleake]

The latest version of Fusion was installed on my computer this past Friday, 10/23. Since then Fusion loads at a snails pace, taking as much as an hour to load. For most of this time in the Windows task manager Fusion's status is reported as "Not Responding". I did a complete uninstall and reinstall, but to no avail. Please help!

Hi Jim, does the failure (or slowness) mean opening a file, or just start up it? If it's slow for opening file, I can take a look into it if you can share me the file. Thanks!

Hi Bruce,

Just starting up. Fusion worked fine before the new install, but now it's unusable. I'm thinking that it is some incompatability with my laptop - it's 3 years old - and the latest upgrade.

FYI, I am teaching a computer-aided product realization course this semester. I have six multidisciplinary (BioE, ID, Systems/ME) student teams designing medical devices with Fusion. We are also using the class as a laboratory to do research on cloud-based 3D CAD collaboration. Autodesk is funding the project. My Autodesk counterpart is Diego Tamburini, but Buzz Kross kicked in some funding as well. We could certainly use your help. Is there someone I can refer my students to when they run into problems?

Hi Bruce,

I'm at work now, using the university network, and Fusion is working fine, so the problem must be with my home network.

Glad to hear that it has been working for your 🙂

Hello, I am still unable to use Fusion on my laptop on my home network, while it works fine when I am at work. I have done a couple of complete uninstalls and re-installs, have tried to connect using the LAN rather than wireless, and have tried disabling the Firewall. Nothing seems to work. At home Fusion does launch, but I frequently get a "not responding" message. Fusion worked fine until about a week ago, but once an upgrade was installed, I started having issues. Any ideas? Thanks.

Hi JM,

A few things to try to help with the load time:

1. In Fusion go to User menu > Preferences > Data Collection.
2. Uncheck the Desktop Analytics, Google Analytics, and "Use my cloud usage" options.
3. Click Apply and then OK.
4. Back in Fusion go to the Add-Ins > Add-Ins tab and select the various options.
5. At the bottom of the screen next to the details option you will see a check box for Run at Startup.
6. As you scroll through the options uncheck the Run on Startup option for each.
7. Then close the dialog, exit Fusion, re-launch Fusion, and see if it helps.

Additionally, to gain some insight into possible reasons try going to www.speedtest.net at home and the office and see if there's a big difference in network connection speeds.

Thanks @baribak . This still helped me in 2019. Turned out that there was a Autodesk CFD Plugin from a test installation which slowed down the startup massivly.

Hi there.

Fusion 360 isn't starting for me at all. As soon as the splash screen goes away Fusion starts to not respond and just hangs.

I've uninstalled and reinstalled but nothing has changed.

Any suggestions?

Hi Jared,

Sorry to hear of your trouble. 

Has Fusion ever worked on this system? If so, has anything changed since it was last successfully run?

Some things to try:

Delete or rename the files NGlobalOptions.xml and NMachineSpecificOptions.xml. They can be found in:

C:\Users\{username}\AppData\Roaming\Autodesk\Neutron Platform\Options\{O2GUID}   OR

/users/{username}/library/application support/autodesk/neutron platform/options/{O2GUID}

See if perhaps your browser cache has been corrupted. Delete it at:

Windows: C:\Users\{username}\AppData\Local\Temp\Autodesk   OR

/private/var/folders/{2-digit GUID}/{Long GUID}/T/autodesk/browsercache

Also, ensure your video driver is the most current one available.

If none of these pan out then let's take a look at your log files. Can you attach those here?

Depending on your OS here are some locations to check for ".log" files:

Windows:

c:\users\{username}\appdata\local\autodesk\autodesk.webdeploy.streamer.log

c:\users\{username}\appdata\local\autodesk\web services\log\webservices.log

c:\users\{username}\appdata\local\autodesk\Autodesk Fusion 360\{GUID}\logs AppLogFilexxxxxxxxTxxxxxx.log

Mac:

/users/{username}/library/logs/autodesk.webdeploy.streamer.log

/users/{username}/library/application support/autodesk/web services/log/webservices.log

/users/{username}/library/application support/autodesk/autodesk fusion 360/{GUID}/logs/  AppLogFilexxxxxxxxTxxxxxx.log

These should help us narrow down what's going on.

Thanks so much for your suggestions. Yes, Fusion 360 had been working on my system for over a year. Nothing changed, that I know of. I ended up doing a clean uninstall by following these instructions. Everything is working fine now. If it happens again I'll post the logs.
