MSI invokes RollBack on perfect install

[Stefan Neumann]

I suddenly have a problem I haven't seen before and cant
figure out why. MSI works perfectly installing packages
and right at the very end it decides to invoke the
rollback process and deletes all its own good work (and
sometimes other files which were there before) before
claiming that the product was successfully installed.

This happens for all packages but only on my workstation -
so it's something local. The same packages install fine
elsewhere. There's no clue I can find in the logs.

I can circumvent the problem by adding /VDISABLEROLLBACK=1
to the setup.exe command but that's of no help if the
install is wrapped by other code.

I'd appreciate any pointers to where I might find what
causes MSI to decide to begin the rollback process.

Many thanks in advance

Install with a command line to create a log file"
msiexec /i <path to your msi file> /l*v <path to a log file myinstall.log>

The log might be large, so use a small msi file if you have one, and post
the log here.

Phil,

Can't seem to find a "small" one - file is 795k if it
fails (ie does the rollback) and 475k if I prevent
rollback via parameter and the install suceeds. Shall I
send it to you via email rather than post here? Which one
do you want to see?

Thanks for offering to help!

There's clearly something going wrong at the end, and the log will also log
the rollback, so somewhere about 60% of the way through the log file is the
general area. Looking for the string error is a good start, but you'll need
to ignore UI related errors. That 795k log file (with the rollback) might be
ok to post here zipped if it compresses well (they usually do). Or zip and
post at a web site if possible.
