The short answer is, you can't do that with the version of InstallShield Express that comes with VFP. This is not really a fault of InstallShield; the limitation is due to Windows Installer file versioning rules, which it sounds like you've already discovered (modified date vs. date created, etc.).

Newer versions of InstallShield Express have an 'always overwrite' feature that enables you to mark files that should always be overwritten during install. I think this started with InstallShield Express X (ten). Anyway it's present in X, 11, 11.5, and the brand new 12 as well. See http://macrovision.com/products/flexnet_installshield/installshield/features/all_by_version.html for the product comparison chart.

Of course, if you use an installer that doesn't generate MSI (Windows Installer) setups, then you're not constrained by the Windows Installer file versioning rules.

>I was able to find that it apparently compares the created date on the file to the modified date of the file on the target machine to determine whether or not it should overwrite. If the created date is less than the modified date on the target machine it will not overwrite? Surely there must be away around this? Any ideas that could be provided would be very greatly appreciated.
