a customer is trying to install our product on his XP-SP2 machine, and fails.
in his "verbose" log, i saw thousands of messages that looks like:
<time stamp> Note: 1: 1402 2: <some registry key>
i tried to reproduce it on a similar machine, but there were only few 1402 messages in my verbose log (which was significantly smaller), and the installation, of course, succeeded.
he runs the installation from a local drive, and says he have full permissions on the machine.
my guess is some machine-related setting that should be changed, since there are a lot of customers who installed without a problem, but i don't have a clue.

i tried to have him remove the SP2 installation, but it was impossible for some reasons.
any idea?
thanks, Yaniv.
here are a few lines from the log he sent me:
