Setup not working

The v3.5.0-R2 installer doesn't work. I always get an error message when setup starts to download additional files saying "Error sending data (12175) A security error has occurred". I've tried to disable any firewall or antivirus, also updated my system but it doesn't seems to work. I'm not sure if it's just my machine out of date (wich I don't think so because previous release worked perfectly), or a general problem.

No file, test, or entry point is named. Start by reproducing the v3.5.0-R2 installer failure when it downloads additional files, then compare it with the previous release that worked. Done means determining whether error 12175 is general or machine-specific and documenting or correcting the cause.
