If these are client OS versions you may be getting a system restore checkpoint 
being created. You need MSI 5.0 and MSIFASTINSTALL to turn that off.

Subject: Re: [WiX-users] questions about installer speed and progress monitoring

Bob,
What kind of failures are handled by this rollback feature? Is it failure
like user pressing "cancel" during installation, or rather disk failure, or
privileges problem, or files conflict, or something else?
I'm trying to asses, how much I need it.

Is it possible to switch off that rollback and related bookkeeping?

Generally I'd prefer 90% of my users have faster install, rather than 1% of
them be able to use rollback when they need it.
Unless this rollback is used by more than 1% of the users... :-)

thanks
Jacek
