The Windows Installer always adds a backslash to paths. I'd be really surprised if it is the adding of the backslash that takes a lot of time. When upgrading lots of existing files the Windows Installer is also preparing for how to rollback all those files that would be replaced. This is why repair/upgrade/patching can take so much longer than initial install.
Remember, initial install is the trivial case. It's the other once that are harder. <smile/> On Fri, Jul 29, 2011 at 10:58 AM, gapearce <mr_gapea...@yahoo.com> wrote: > I've got an installer that has to install several hundred files, and it > seems > to take a long time to compute the space requirements, especially on an > upgrade. > > During this phase, I see in a verbose log that there is a lot of work going > on to just add a backslash to the end of all of the folder names being > updated. > > There's a message like this in the log for each folder: > > MSI (c) (FC:1C) [13:25:08:257]: PROPERTY CHANGE: Adding > dir892D072CCFBC52F1571AE901E4A5BC6F property.
