To schedule it before any UI is shown, it must be sequenced in the installUIsequence, probably before CostInitialize.
But this will remove the old version before the user has seen any UI and won't be able to stop uninstallation. In Windows Installer it would be more common sense to perform the user "interview" before doing system modifications.

Subject: Re: [WiX-users] Obtaining a property and running an exe if,and only if a property contains a value Hi Sean, To get the registry values use the <RegistrySearch> element to set the value to a property. Then use a <CustomAction> with a condition using that property. Schedule that custom action after InstallInitialize in the InstallExecuteSequence.
