slow installer

Hi,

We have a MSI package with 289MB, which installes about 10.000 files
and and 550 directories.
On some machines we timed the un-install with 22minutes and the
install with 39minutes.

-- 3 minutes just to start the executable (i.e., see a window)
-- 5 minutes to extract the MSI
-- 6 minutes decompressing the MSI
-- 8 minutes "preparing to install"
-- 17 minutes to do the actual file copying installation

is there anything to speed up the process?
Or are these numbers fine for the amount we install?

Thanks,
Andreas

What's the exe? That's where you've got 14 minutes before the MSI even
starts, assuming decompressing is still that exe.

If you have System Restore enabled that may have an effect. On MSI 5.0
MSIFASTINSTALL might help. Apart from that, a lot of time is preparing to
undo the install (and the uninstall) of all those files if the install (or
uninstall) fails and rolls back to restorte the system to its previous
state, and that has a cost. DisableRollback might save you some time at the
risk of an install that won't recover.
