Getting an error about not being able to generate a certificate

[Rod]

I've just downloaded the latest Fiddler2 and put it onto my PC. I admit that I'm not a Fiddler guru, but I know enough to use it somewhat. I'm trying to determine what's going on with one of our websites, so I downloaded the latest Fiddler2, installed it and fired it up. Then I brought up my browser (IE11 on Windows 7 Ultimate, 64-bit). The website is protected with SSL, and so when I went to look at the header information Fiddler immediate told me that it was encrypted, but that it could decrypt it. I told it to do so, and then I started getting these popup messages from Fiddler2, over and over again. I don't know what to do about it, so help!

This indicates that your Windows private key store is corrupt. The first few steps here are typically sufficient to fix this: http://fiddler.wikidot.com/certfix
