Office click-to-run 365, VL etc will not let you add an app if already run with excludes in the XML

 If you have previously excluded Office apps from your install you may find that re-running without them excluded does not install them.

It seems Office click-to-run keeps a record of the initial excluded apps in the registry.

Use regedit.exe to take a look in the following path for the 'O365<edition name>.ExcludedApps' key.

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration

Remove any excluded apps and rerun the install.
