    So I'm on a server with no internet access (trying to debug an intranet application).

    In Fiddler Options, OI have "Check for updates on startup" cleared, and "Offer upgrade to beta versions" cleared as well. Seconds after starting it, I get an exception:

    Awww, Fiddlesticks!

    Fiddler has encountered an unexpected problem. If you believe this is a bug in Fiddler, please copy this message by hitting CTRL+C, and submit a bug report at

    VersionCheckFailed: Server Response Code = 0

    Fiddler v4.6.2.3 (x64 AMD64) [.NET 4.0.30319.34209 on Microsoft Windows NT 6.2.9200.0] 

    Shouldn't it, y'know, not be checking for updates when I explicitly told it not to? Application dies, game over...

    I am really sorry about this. It's a known problem and it's already fixed in the latest beta you can download. You can also start fiddler with the -noversioncheck console switch as a workaround.
