Hi there,
my MSI installer is made with WiX 3 and I wonder if there is a
possibility to uninstall the current installation (if any) of the
product and then installing the new one?
I am asking since I don't want to do a major upgrade every time I do a
little change, but I want the use to have the possibility to start an
up-to-date setup of mine without uninstalling a previous version.
I figured out that I have to do the following on the command line to
have nearly what I want:
start /wait msiexec /uninstall {AB00DB53-6902-44c2-8537-BC3B8283A21D}
/quiet & msiexec /I "Application.msi"
where the GUID given is the product ID of the MSI (like I said, no major
upgrade).
So is there a was to specify a similar behaviour directly via WiX?
And, if not, is there a way to do it in a single MSI call? I played
around with properties like "REMOVE=All" and "REINSTALLMODE=vamus" but
with this properties the there appeared no GUI to select the features or
to accept the licence. I know, I tell MSI to reinstall all feartues -
but, isn't there a way to say "Remove all features and let the user
choose to what to reinstall?".
Regards and thanks,
Tom
