Hi Bob,

The same can happen on, say, XP machines. If the browsers security settings
are set "too high" then the required Authenticode plug-in (ActiveX) from
Microsoft can't be installed (or executed) and the certificate request
process fails.

In your case, if IE failed and FireFox succeeded then you had different
security settings in the browsers. On your machine, the FireFox security
settings were not as strict as the IE ones.

BTW, the problem is not UAC per-se. But in Vista, Windows Server 2008,
Windows 7 and Windows Server 2008 R2, the required components are not
available any longer to handle "In the file" certificate requests. So the
certificate always goes into the certificates pool and you have to export it
(e.g. to .PFX) in order to code-sign files.
