If you haven't started the install yet, you could pass those properties on the
command line. Alternatively, the first parameter in the UIHandler callback
("context") is (can be cast to) the MSIHANDLE for the install. The example
callback in MSDN casts it to an MSIHANDLE when it calls MsiFormatRecord(). I've
never tried an MsiSetProperty() on it though.

Subject: [WiX-users] Can msi external ui write to the MSI properties?
Hi,
I'm trying to see if I can use msi external ui for my project. Will I be
able to get an input from the user using msi external ui and then store
that, lets say string, input from the user into one of the msi properties? I
feel it can't be done because the external ui would probably be running in a
separate process and it wouldn't have any handle to the currently running
msi to set the property. Please assert my understanding.
Thanks,
Pratap.
