As of the beginning of June, we've started seeing a spike in the certificate-related issues out in the field for our production app. This spike has caused an 8-fold increase in the number of certificate-related tickets we see - we've been unable to reproduce these issues in house, and examination of our customers' machines has showed that their Personal certificate store appears to be corrupted. When we installed Fiddler .NET4 on their machines for debugging purposes and attempted to enable HTTPS traffic, we saw the attached "Creation of the interception certificate failed" - Googling this error yielded one possible solution of renaming or deleting the folder under C:\Users\[username]\AppData\Roaming\Microsoft\Crypto\RSA, and another solution of installing the FiddlerCert addon.
At this point, we believe either a recent Windows Update or potentially even new malware is responsible for this spike. We wanted to see if the folks in the Fiddler community have also experienced a recent spike in this issue, and if so, then are there any other ways to resolve the issue on a machine once it appears?
