I am trying to monitor some SSL traffic to understand the flow between
two web sites/applications. However when attempting to read the HTTPS
packets, Fiddler v2.2.4.2 beta complains


---------------------------
Unable to Generate Certificate
---------------------------
Creation of the interception certificate failed.

makecert.exe returned -1.

Results from C:\Program Files\Fiddler2\MakeCert.exe -ss my -n
"CN=DO_NOT_TRUST_FiddlerRoot, O=DO_NOT_TRUST, OU=Created by
http://www.fiddler2.com" -eku 1.3.6.1.5.5.7.3.1 -r -cy authority -a
sha1



Error: Can't create the key of the subject ('JoeSoft')

Failed

-------------------------------------------


---------------------------
OK
---------------------------



This seems to appear of SSL sites i visit so i had to disable the
Decrypt HTTPS Traffic option. Any ideas what this error is really
about?

This means that your machine's certificate store configuration is
corrupt and hence Fiddler can't use it.

I tried to delete any key with name 'JoeSoft' but hit the following
error

Failed to delete container 'JoeSoft' -- Unable to format error message
8013141C

I did not find any cert made by Fiddler in the machine cert store.

Aaron
