Fiddler unable to generate certificate

• So go here: C:\Users\\AppData\Roaming\Microsoft\Crypto\RSA\
• Select all the files (named with UUIDS).
• Move those files to your Desktop or other folder outside AppData dir.
• Launch Fiddler, go to Tools | Fiddler Options | Enable HTTPS decryption
• See that it works this time (hopefully).
• Move the files back from their temp location (i.e., Desktop),
• to their original one: C:\Users\\AppData\Roaming\Microsoft\Crypto\RSA\
• When one of the files asks whether you want to replace the existing one, skip it.
