Hey,

So I wanted to give Fiddler Everywhere a try, but for some Reason Fiddler4 (2?) now refuse to decrypt HTTPs Traffic.

 

19:50:40:5619 Assembly 'C:\Users\xx\AppData\Local\Programs\Fiddler\CertMaker.dll' was not found. Using default Certificate Generator.
19:50:40:5644 /Fiddler.CertMaker> Using .‰+˜ for certificate generation; UseWildcards=False.
19:50:50:4136 /Fiddler.CertMaker> Failed to identify private key location for Root Certificate. Exception: System.Security.Cryptography.CryptographicException Der Schlüsselsatz ist nicht vorhanden.


It tells me CertMaker.dll is missing,  so he Fallback to Default Generator, but that just post some random rubbish Icons. The Last Error Message is telling me, that he cannot find the Private Key (I installed certificates Multiple Times)

Just Curious if there is a way to fix that issue?

Try to reset all certificates through Tools > Options > HTTPS > Actions > Reset All Certificates (you can also remove them manually as shown here) and then install and trust the Fiddler Classic certificate again.

No answers yet. Maybe you can help?
