A software problem has caused Fusion 360 to close unexpectedly (2)

[arzoman85]

Hi! After the latest update Fusion 360 crashes on launch with the error in title. I did clean uninstall and re-installed the app several times, updated all my drivers, updated Windows, checked the internet settings, turned off the antivirus, but nothing helped. Please help me to solve the problem. Regards.

Windows 10 

Intel Core i7-8700 

NVIDIA GeForce GTX 1080

Hi @arzoman85. Thank you for posting!
Did you send the error report after the notification appeared? If not, you can do so and send its number. We will then be able to check the potential cause.

In the meantime, please tell me if you used these instructions during the clean uninstall? If not, you can try again and after reinstalling, try running Fusion 360.

Another cause could be that you are using Duet display app. If so, try uninstalling it following the instructions below:

1. Go to Control Panel -> Add or Remove Applications and select Duet Display.
2. This will ask you to restart your PC to uninstall.
3. After you reboot, open Control Panel -> Add or Remove Applications and confirm that Duet Display as well as Kairos Display are removed from the list.

Note: On some occasions you must uninstall a remaining component of Duet because Windows separated them during the uninstall process. If so, just select the component, uninstall and restart your PC once more.

Hi, Rafal. Thank you for quick response. Yes, I used the instructions to do clean uninstall, but it didn't help. I don't have Duet display app, so I hope the error report will make clear what is the cause of the crash.

The report number is 308877750

@arzoman85 thank you for the report number. I'll try to gather some more information and back to you ASAP.

@arzoman85 I've some updates and additional questions. 

You mentioned having updated all the drives. I am wondering if the drivers for your NVIDIA card have been downloaded directly from NVIDIA website? If not, please try that.

If it still fails:

• How many monitors are you using?
• How are these connected (docking station, etc.)? 
• Is Fusion 360 launched on the primary monitor?
• Does changing the environmental variable for your graphics card allow you to launch Fusion 360 with no crash?

How to add an Environment Variable:

1. In the Windows Control Panel, search for "Environment Variables".
2. Click "Edit the system environment variables".
3. At the bottom of the System Properties dialog, click "Environment Variables...."
4. Under "User variables for <user>", click "New".
5. Enter "QT_OPENGL" within the Variable name.
6. Enter "angle" within the Variable value.
7. Restart Fusion 360.
8. If the setting causes further issues, repeat steps 1-3.
9. Edit the "QT_OPENGL" variable, entering "software" within the Variable value.
10. Restart Fusion 360.

I always download GPU drivers via GeForce Experience app, as far as I know there's no difference between the app and NVIDIA website downloading. I have only one monitor. I changed variables, entering "angle" and "software" values, but no success. The thing is that I've been running Fusion on my PC already two years and never had problems with it until two latest Fusion updates. During the previous one, I faced with the same issue, but re-installation solved it. Now I'm stuck. By the way, before Fusion updating, my  Windows was also updated. Could it be the cause of the problem?

Hi, Rafal! Are there any updates on my issue?

[Rafal.Chlod]

Hi @arzoman85. Thank you for your response. If you didn't make the update yet, please check the latest graphics drivers version from yesterday.
You can also try to downgrade your Windows version, if it is possible. It can be one of the causes.

There are some steps we didn't check. You can find them in this article.

[arzoman85]

I've updated my graphic drivers today, but unfortunately it didn't help. If there are no other solutions, I'll try to downgrade my Windows, but still can't understand why this happened.

Finally, Windows re-installation solved the problem
