MacOS Installation error: [Errno20] Not a directory

Anonymous — Tue, 24 Dec 2019 19:52:15 GMT

When I run the Fusion 360 Client Downloader, It gets to 99% then gives me the following error:

[Errno20] Not a directory: '/Users/<User Account>/Applciations/Autodesk Fusion 360.app/'

I have tried a manual clean uninstall and rebooted my computer to no avail. I have also run the installer application with administrator privileges, to no avail.

I am running MacOS 10.15.2 on a Mid 2015 MacBook Pro. I've attached the installer log as well as a screenshot of the error code.

Hello @Anonymous,

Sorry for the delay. Its seems you were having "Not a directory" & proxy related errors in your log.

Try the cleanup tool to perform a clean uninstall and then restart the computer.
Follow the steps outlined here, "How to configure proxy server and firewall for Fusion 360 (macOS)"
Then reinstall the application again.

Ni, Natasha -

I tried both of those things with no luck. I also had some issues running the Cleaner.app -- My mac said simply "Fusion 360 Cleaner.app can't be opened" and I had to modify some of its permissions in terminal to get it to work. Anyhow, once I got that working it seemed to delete all the appropriate files. I changed my firewall and proxy settings, restarted my computer, and downloaded a fresh copy of the client downloader. It once more got to 99% before giving me the same error. I've attached the log file from this one. Any further advice?
