@s1536094 @If you right click on the installer and run as an administrator does the install go through? This kind of error is usually a permissions error but I will check with out engineering team as well.

Hi Rajkumar

I tried installing as administrator. It made no difference. This is not surprising; the user already has admin privileges.

I have attached the log file which resulted when running "Fusion 360 Client Downloader.exe" as admin

By the way, I saw a message in the log file saying that "The host is accessible.", so I tried tried a PING The results are below

Hi Doyool Chung

I tried doing as you said; deleting files, reboot, reinstall. The behaviour is still the same, it does not install.

What do you see in the log file that is unexpected?


Please find the log file attached.

@s1536094 I will let Dooyoul look at the new logs but had another engineer from his team also look at the logs and suggested the below:

"This could happen when Defender or other anti-virus are blocking the access for certain file. And turning them off may solve this issue."

Do you know of any recent changes you made to Windows defender or any new anti-virus installed on the machine?

Hi @s1536094 

Thanks for sharing log file.  Looks like your Windows OS won't matched with Fusion 360 system requirements.
Please check below Fusion 360 system requirements.


update: I see that you may updated OS to Windows 10 after first try. The error message is the same as you shared in first place. Please give a try with above @RajkumarIlanchelian  suggestion.

Yes, I upgraded from windows 7 to windows 10 after I saw that message. The warning about the OS went away, but now I have the current issue:  CantOpenError: unable to open database file

Message 9 of 10

I have temporarily  turned off bitdefender. "Virus and threat protection is turned off"

It does not seem to have made any difference. Please see the attached log file.


Thanks for your efforts

Hi @s1536094 ,

Do you see a file named 'registry' in the folder C:\Users\Claudia Slegers\AppData\Local\Autodesk\webdeploy\meta ?

If yes, can you try to open that file with a SQLite browser tool which can be downloaded from here.
