This is error: ssl.SSLError: not enough data: cadata does not contain a certificate (_ssl.c:4014)

Hello,

No, your link in that thread is not active, and what customer said didn't help. I did all the things he did, but still the same

Thanks,

Ivan

So what i did. I turned off all apps which start with windows, turned off firewall, turned off windows defender, clear SSL in Internet options, reset internet options to default, clear cache, clear temp, PC is on LAN, not on wi fi. What else to do?

@ivan_urosevi Is it possible you can try with another network if possible , say a mobile hotspot, maybe? Also which country are you located? We have seen (rarely) some install related issues based on the location which may need some looking into with logs etc.

It's not problem with internet, or my location (I am from Serbia, btw), since i managed to install it on clean windows installed on virtual machine. But the problem is that i must install it on lap top which is connected to my machine, and i cannot format it, since i have many different software there. I tried to install on 3 different pcs, which already have many certificates installed, and it only worked in 4th, virtual machine. So something else is blocking installation, i assume some other certificate, but how to discover which one?

Uninstall the Celik software (Citac Elektronske Licne Karte). This software installs some certificates which mess up validation during the install process of Fusion 360.

[Update] Ok, I just noticed that this remedy doesn't work for you. It worked for me, though.

This worked for me! I got two separate errors until I uninstalled the Celik app. Thanks!
