I read that to mean that the component is already installed and doesn't need
updating from your new setup, perhaps because the versions are identical. Your
RemoveExistingProducts is probably sequenced to run at the end of your install,
so it's applying update rules. In some cases you might see a message something
like "{guid} will not be installed because the same or a higher-versioned
keyfile is already installed", the same situation.

Subject: [WiX-users] Understanding component states
Hi,
I'm having trouble understanding why one component is failing to get
installed. I'm doing a major upgrade, and this component exists in both
the old and new versions of my package. If I manually uninstall the old
version and then do a normal install of the new version, the problem
component does get installed.
Looking in an MSI log, during the InstallValidate action I see:
MSI (s) (C4:94) [15:51:13:079]: Component: SPCControls_dll; Installed:
Absent; Request: Local; Action: Null
I have a relatively simple installer with a single feature that contains
everything. This component doesn't have any conditions. I dark'ed this
MSI and our previous MSI (which handles a major upgrade just fine) and
they both show identical markup for the component in question. None of
the other components seem to have problems.
What else should I look for to understand why the action for this
component is getting set to 'Null'?
Thanks,
Don Pratt
