Stop prompting me to check for updates

It's incredibly an annoying prompt that occurs every. single. time. i open up fiddler.


Check for updates behind the scenes if an update exists and only let me know when an update exists

Hi all,

Sorry for the inconvenience caused by the prompt. You can stop it from occurring by setting the "fiddler.updater.CheckFreshness" to false as Eric says.

Yes, it's the "What's that smell?" prompt.


I'm running v5.0.20182.28034 for .NET 4.6.1.


fiddler.updater.lastbegged is set to yesterday's date (5/23/19)

Hi, James-- Sorry for the annoyance; is the prompt the "What's that smell?" prompt? Which version do you have installed (via Help > About)?

You're definitely not supposed to see this dialog if you have version checking enabled inside Tools > Fiddler Options. 

You also shouldn't be prompted on "every" startup-- if Fiddler is working properly, it should be writing the date of the last time it asked you to "fiddler.updater.lastbegged" inside Computer\HKEY_CURRENT_USER\Software\Microsoft\Fiddler2\Prefs\.default

As it stands, this area is pretty buggy-- Telerik hasn't released a new version in nearly a year (previously, new versions came out every few weeks) and regardless of your version checking settings, the current version of Fiddler will ignore them and perform "critical update checks" anyway; you can recognize this from the light blue line with the tooltip: "Critical updates check. Switching this off is not recommended and could be done using the - noversioncheck command line switch." That line contains a typo, there should be no space between the dash and the noversioncheck token.

So there's no need for the begging prompt anymore.


You might try typing the following in the black quickexec box below the Web Sessions list and then hit enter:

  prefs set "fiddler.updater.CheckFreshness" false

...but if your preferences are not being stored to the registry properly that will likely not help.
