Another Fusion 360 won't start

[ian.shatwell]

Can anybody suggest any way forward?

I have had no recent problems with Fusion 360 until today, but now it will not start.

Double clicking on the desktop icon produced the initial small splash screen, then the main window with the Fusion 360 central branding, then went to a blank screen except for two view manipulation cubes. It then hung.

Manually uninstalling and reinstalling has not helped. I now get a blank screen and hang immediately after the main window opens. I still get the initial splash screen. According to task manager there is an Autodesk Fusion 360 subprocess running at what looks to be a maxxed-out single-threaded task (i.e. 9-10% CPU usage on a 6 core hyper-threaded system).

Killing off the main window leaves two processes running: the analytics client service and a console windows host. They need to be killed manually before Fusion 360 can be restarted.

Using Ctrl-Shift to launch the utilty menu allows a network test to show there is no problem there, but trying to gather the support info quickly crashes out without producing the aggregated zip file. Various log files are attached but this might not be everything that should be gathered.

Neither Reset nor Repair Fusion 360 made any difference. The login prompt was not presented.

Anything else to try?

As you guessed, your log files are not complete.  Follow this webpage directions to get the complete log file set and then post it.

Hi John,

Thanks for responding so quickly.

The page that you linked to for gathering the log files only states to use the 'Gather System Info' from the Service Utility Menu, and further links say how to gether it from running Fusion360, which obviously is not possible. Unfortunately, as I stated in my original post, the Utility Menu crashes while doing this. If you can point me to which logs are needed, presumably under AppData\Local\AutoDesk or AppData\Local\Fusion360, I will bundle them up. I have now attached what logs the service utility does gather, and the installation log which one of the further links mentioned.

Kind regards,

Ian

Your autodesk.webdeploy.streamer.log shows the error below.  Here is the Autodesk page to troubleshoot this error.

Hi John.

Still no luck.

Tried the single threaded installation as the article you pointed to said. Still the same errors.

Checked if Windows Update had done anything today. It had - KB5017328. Tried to find out about it, but got DNS errors trying to reach support.microsoft.com. Strange.

Changed my DNS server from 1.1.1.3 to 1.1.1.1 and can reach the support site. 1.1.1.3 filters out malware and inappropriate adult content. Not sure which one Microsoft counts as.

Uninstalled and reinstalled Fusion 360. Single threaded again, just in case. No errors in the installation log this time, but it still will not launch.

Try to gather the logs. Utility menu still crashes before it gathers everything and creates the zip file.

Check WebServices.log - two missing DLLS: libcrypto-Ad-1_1-x64.dll and libssl-Ad-1_1-x64.dll.

DLLs with the same names except Ad (i.e. libcrypto-1_1-x64 and libssl-1_1-x64 exist under the webdeploy\production\hexstring folder, so trying copying those to the missing names in case it is just a packaging error.

Fusion 360 still crashes with a blank screen but the webservices log shows it got further.

I do not see any errors in your autodesk.webdeploy.streamer.log and it seems to have installed.  Have you restarted your computer since you did the install?  I am out of ideas, sorry.

[ian.shatwell]

Yes, the computer has been restarted, and I rebooted again just to check. Still no luck.

Thanks for your help.

I eventually got it working by uninstalling every AutoDesk product I had installed along with anything they dragged along, no matter how minor - everything which mentioned AutoDesk as the vendor under Windows Settings->Apps->Installed Apps (so DWG TrueView, ScreenCast, MeshMixer, Parameter IO, etc), then deleting any folder related to AutoDesk or Fusion360 under AppData\Local and AppData\Roaming, then reinstalling Fusion 360. Fortunately my tool and postprocessor libraries were cloud-based.

Now to reinstall everything else.
