Hello!

Please, add clarity about REINSTALLMODE property.

According to Microsoft documentation, it useful when installation required running from the source package and re-caching the local package.

Additionally, recommended not use the v reinstall option code for the first installation of an application or feature.

Unfortunately, I did not find description of behavior when v reinstall option is not set.

When I need to set v option in routine? (Reinstall, first install, small update).

Can I set REINSTALL and REINSTALLMODE property in Windows Installer database, without command-line parameters?

An InstallShield docs explain further, that v forces re-cashing from msi package to target system. Thus, every minor update needs to be set v reinstall option?

That's correct, every minor update that is shipped as full .msi file needs to set the v in REINATLLMODE. If it ships as a .msp patch this is not required. You cannot set the v inside the package it has to be set outside. Setting REINSTALLMODE=v doesn't hurt for a first time install.

You shouldn't set REINSTALL=ALL for a first time install, as this will only reinstall what was installed before, which in this case is nothing.
