I recently ran into an issue with Fiddler where after upgrading I was unable to decrypt HTTPS traffic. I tried resetting the certificates, every single walk through on the Telerik site, I even did a complete uninstall, searched the registry for fiddler, removed all references, located all “DO_NOT_TRUST” fiddler certificates in the Certificate Store and just wiped them out.
Still Nothing. God dammit.
and then after I cooled down I found this answer on a google group. I’m re-posting here to help spread the love.
