Hello,

Trying to download PREPAR3D® V5.2 ACADEMIC, I get an error:

The connection for this site is not securecloud.prepar3d.com sent an invalid response.
Try running Windows Network Diagnostics.

I've tried different machines and Firefox and Edge

Please help!


Thank you,

Hello,

We recommend that you check your windows hosts file to ensure that secure.prepar3d.com has not been blocked from accessing the download page.

The hosts file is a computer file that is used by the operating system to map hostnames to IP addresses, Its possible your virus scanner or firewall software has added an entry to your host file that blocks the site.
  • 1. Type %WINDIR%\System32\Drivers\etc into your windows search bar
    2 Click on the folder to open
    3. Right click on the hosts file & open with Notepad
    4. Review & delete any entry that refers to Prepar3D
    5. Save the updates and try accessing the site again.
Updates to the host file will require administrator privileges.

Cheers,
Chris

My solution was to use a VPN to download, seems like an issue with my internet service provider.
