I’m trying to run FiddlerCap Web Recorder.  When I check ‘Decrypt HTTPS traffic’ as True, I get a dialog box appear titled ‘A note about HTTPS Decryption”, upon selecting okay, the 'Decrypt HTTPS traffic'  appears as false again and a note in the bottom left footer of the application states ‘Sorry, unable
to create root certificate’. 

I'd appreciate any help in resolving this.

Thanks.

Hello, Anthony--

Unfortunately, FiddlerCap doesn't offer much diagnostic information for errors like this. Have you ever run Fiddler (not FiddlerCap) on the machine in question? It's possible that Fiddler's certificate is conflicting with the FiddlerCap certificate.

Is the machine in question domain-joined / managed by corporate policy?

Hi Eric, thanks for your reply.  

I did initially install Fiddler but didn't runt he program. I then uninstalled it and downloaded FiddlerCap.  Would this likely cause conflict? 

Yes, we operate on corporate policy here.  

Appreciate your thoughts.  

Thanks

Hi, Anthony--

Simply installing Fiddler will not cause a conflict; if you'd run it and enabled decryption it could, conceivably.

The most likely explanation is that your IT department has used Group Policy to lock down the Windows Certificate stores such that FiddlerCap cannot generate the certificates it needs to perform its function. Short of talking to your IT department (or capturing only HTTP traffic) I'm afraid I don't know of any workarounds.
