By installing the CertMaker in the add-ons list it should resolve the issue. I tried and it is not working. My environment is Windows 7.
Could you propose another resolution? I tried a lot of thinks indicated in your post without success.
To get help with this, you'll need to provide far more detail about your situation. For instance, after installing the CertMaker add-on, it's not possible to get the error message described in this thread, so I'm guessing that this isn't what you're seeing.
1. What have you tried thus far?
2. What exactly fails?
3. What do you see in Fiddler's LOG tab?

1. Navigate to
2. Delete the contents of the folder. (I did create a backup of the folder first)
Yes, that tends to resolve the problem, but it's potentially risky. The procedure you describe deletes all of the user's private keys from disk; this can be entirely harmless, or very very bad (if the user had any keys for non-Fiddler certificates).
These days, a safer and better choice is to switch to the Certificate Maker addon (or switch to CertEnroll as the generator).
