is it possible to modify a msi package to require MSI 4.5?

[Sergiaws]

I wish to install some applications, but I can't do it cause the applications require a newer MSI. Is it possible to bypass that requirement with Orca MSI editor? I never could find that section myself.

It's in View > Summary Information... in Orca

Or Tables > Summary Info... in InstEd

Change Schema to 405 to use Windows Installer 4.5

But you'd need to check that all the tables are supported in 4.5. This page lists the tables and notes if they are not supported in older versions:

There might be other incompatibilities but seems to work for me for SketchUp Make 2017 on Vista (with the extended kernel).
