Applying patches in silent mode

[KingVoodoo]

The documentation says you have to set
REINSTALL=ALL and REINSTALLMODE=omus
if you want to apply a patch in silent mode.
Why? What will happen if you don't set the properties?

Thanks.

In MSI 2.0 if you don't set these properties the patch will not be applied. When you run the patch with a UI the default PatchWelcome dialog sets these properties for you.

MSI 3.0 may not have this limitation as the mechanism determining how to modify the target paching from a patch has changed significantly. I've not had the opportunity to test this though.

Thank you very much 😄
