I read the tutorial and I seem to be stuck here:
After the check has run, we can take the appropriate actions based on the
existence and value of the properties involved:
<CustomAction Id='AlreadyUpdated' Error='Foobar 1.0 has already been updated
to 1.0.1 or newer.' />
<InstallExecuteSequence>
<Custom Action='AlreadyUpdated'
After='FindRelatedProducts'>PATCHFOUND</Custom>
...
</InstallExecuteSequence>
For some strange reason, small updates and minor upgrades cannot be run simply
by clicking on the .msi file—they give the error: "Another version of this
product is already installed." We know, stupid... Anyway, you have to start it
with the command:
The statement "we can take the appropriate actions based on the existence and
value of the properties involved". I don't know how to run actions based on the
existence of a property. I am assuming that it refers to PATCHFOUND. I want to
stop services, copy files, restart service. Simple?
Thank you.
Kevin
