Deactivate anti-malware software which is scanning encrypted (https) internet traffic or other proxy or network analyzing software you might have installed.

The SEB installer bundle and the installers of the dependencies connect to Microsoft servers and use certificate pinning. Such above mentioned tools replace the root CA certificates in Windows to perform a Man-in-the-Middle attack to be able to analyze encrypted network connections. Those installers fail then.

Антивирусов нет, только брандмауэр windows и его я полностью отключил. Проблема не ушла.

[danschlet]

Just for your information: We can give support to requests in English, German, Spanish and French. Russian is not a supported language, I'm sorry.

[marat123456]

The antivirus is disabled. The problem has not disappeared

[danschlet]

Maybe @dbuechel can help.

Microsoft has updated their WebView2 bootstrapper (yet again). @danschlet We might need to switch to a fixed-version setup as we already have it with CefSharp.

For the meantime: To use SEB 3.2.0, first install all the required dependencies as listed below:

• .NET Framework 4.7.2 Runtime: https://dotnet.microsoft.com/download/dotnet-framework/net472
• Microsoft Edge WebView2 Runtime: https://go.microsoft.com/fwlink/p/?LinkId=2124703
• Visual C++ 2015-2019 Redistributable: https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads

Then install the SEB 3.2.0 MSI for your platform (either x86 for 32-bit or x64 for 64-bit machines):

• https://github.com/SafeExamBrowser/seb-win-refactoring/releases/download/3.2.0/SEB_3.2.0.338_x64_Setup.msi
• https://github.com/SafeExamBrowser/seb-win-refactoring/releases/download/3.2.0/SEB_3.2.0.338_x86_Setup.msi

Yes, please do that @dbuechel, seems like the only way how to prevent issues with these Microsoft updates.

[dbuechel]

The issue is now fixed with the latest release version 3.3.0.

[nebuduk]

Installation worked fine, thank you very much for your promt help and answer!
