install pronlems first time user

Hi i thought i would give fusion 360 a go to design some bits for my 3d printer, just basic stuff really. Ive tried to install the personal use download but it comes up with an error and wont even install. Not a good start i think. Ive attached the error message and the last bit of the install log to see if their is any kind person who can help me out. Its a shame because all the tutorial videos on youtube rave about fusion, so at the moment im not too impressed.

many Thanks in advance

Nick

This is not a Fusion bug. This error means the encrypted download stream is being altered or interrupted on the system or network before Fusion finishes installing.  Fusion’s installer uses a secure streaming download service. If anything intercepts or inspects HTTPS traffic, the installer will fail with this exact SSL error.

Most common causes:

Antivirus or endpoint protection performing HTTPS/SSL inspection

Corporate firewall or secure web gateway (Zscaler, Forti, Sophos, Palo Alto, etc.)

VPN client (even if “connected but idle”)

Proxy or transparent network inspection

Corrupt Autodesk installer cache

I would try the following:

1. Temporarily disable anything that inspects web traffic

Before reinstalling, temporarily disable:

Antivirus web protection / HTTPS scanning

Endpoint security agents

VPN clients

Secure web gateway or proxy agents

If this is a corporate network, the following domains must be allowed without SSL inspection:

*.autodesk.com
*.autodesk.io
*.akamaized.net
*.amazonaws.com

2. Clear Autodesk installer caches

Close all Autodesk applications, then delete the following folders:

C:\ProgramData\Autodesk\AdskLicensing
C:\ProgramData\Autodesk\ODIS
%LOCALAPPDATA%\Autodesk\Web Services
%TEMP%\Autodesk

3. Reboot the computer after deleting these folders.

Verify system time and TLS

Make sure:

System date, time, and time zone are correct

TLS 1.2+ has not been disabled by local policy

(Optional) From an elevated command prompt:

w32tm /resync

4. Test without proxy settings (optional but helpful)

From an elevated command prompt:

netsh winhttp reset proxy

5.  Then retry the install.

I would use the Full / Offline Installer (recommended workaround)

If the issue persists, bypass the web installer entirely:

Sign in to your Autodesk Account

Download Fusion 360 – Browser Download / Full Installer

Run the full installer instead of the web-based installer

This avoids streaming downloads and is the most reliable solution on restricted networks.

Hopefully this gets you what you want.  I suspect it is likely just a corrupted installer.  

Good Luck!
