FOG newbie here. I also had the error “Unable to install CA certificate” when attempting to install the FOG Client 0.12.0 with HTTPS on Windows 10. Bumping this post because it was hard to find since most of the keywords I searched are in the screenshots, not the actual text. Hopefully if anyone else has this issue they’ll find it a bit faster.
The Smartinstaller_fixed-tls.exe corrected the issue on my machines as well.
My logs also showed the same lines:
Middleware::Communication ERROR: Could not download file
Middleware::Communication ERROR: The request was aborted: Could not create SSL/TLS secure channel.
