I have a similar problem, and I see this message was ignored by the
community. Maybe it is a stupid question? I dunno - but I have the problem
too.
I noticed my MSIHANDLE is one ('1') before installation of the files. AFter
the files are installed, the MSIHANDLE is eight ('8').
Before installing the files, I can log custom messages to the log file from
my DLL, no problem. But after the files are installed, (just before exit
dialog), I can no longer log any messages. The MSIHANDLE is eight, and the
result from MsiProcessMessage is zero - means no action taken.
Is the change of handle just a coincidence? I tried using '1' for the
handle always (of course, just as a test), and it still doesn't work.
Handle one must have been closed somewhere along the line.
Can someone please shed some light on this?
