Hello,

yes, that problem a bit hard to spot because it does not stop at error.
The installer actually verifies a list of files and stores the cert check
results in a counter.
By debugging the crap out of that installer, I was able to identify the failing
one ;-)
Armed with that knowledge, one can go back in rather long trace log and find
the following offender:

..
--- snip ---

"ie7.cat" is the failing one -> 0x800b0003 -> TRUST_E_SUBJECT_FORM_UNKNOWN

All other files are successfully verified.
And of course - pPolicyStatus->dwError - is really checked ;-)
