Fusion does not launch

[baksabass]

When I try to start Fusion, the initialization window appears and then disappears after a few seconds. After several attempts, the Fusion Service Utility window appears. I ran a Network Diagnostic test with this result: https://notifications.api.autodesk.com/health (found an error here). Potential network connectivity issue... I ran a Repair Fusion command where it also found an error. I have attached the log file. Thanks in advance for your help!

In the meantime, I tried to reinstall. I launch Fusion Client Downloader.exe. It runs through and then Errno 13 indicates an error. I have attached the log file.

Please try below steps to install Fusion. 
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

If someone else has this error occur, I was challenged by this for a few hours even after trying the steps above.

Reinstalled a few times and I still had the issues.
I had to run the installer as administrator(right click, run as administrator) in order for it to work finally.😅
No issues since.

Yes, it is important that you have administrator rights!

Crazy thing is everything worked fine until a windows update. That's what turned everything on it's head... Took me a minute to figure out the administrator thing because I never had that issue before and theirs 1 user on my desktop which always had admin rights..
