[wix-users] IIS Extension Certificate Installer & TARGETDIR

[Andy Clugston]

Hopefully to clarify a bit -- the goal with setting TARGETDIR on the
command line when invoking the package was to force to C:\ rather than
allowing WindowsInstaller to select D:\. We are just testing now to see
if/how this might make a difference.

Would it make more sense to set ROOTDRIVE?

Either way, it feels like there may be a logic issue with the extension. It
is not clear to me what is causing it to think it needs to uninstall the
cert. It is calling the DeleteMachineCertificate custom action.

Rob, what should I be searching for in the verbose log? I am diffing
between a good and bad log and there are only a few things that are
different and they are related to the IIS custom action and ROOTDRIVE and
TARGETDIR being different.

Thanks.
