[wix-users] preventing double installs: per-machine & per-user both getting installed

[Alan Sinclair]

*>  Have you considered wrapping your MSI in a Burn bundle that does the
detection, or write a UI for the MSI the runs a custom action early in its
life *

Management decided we can't use Burn
Can a custom action DLL be run before the UI Sequence, and have input into
the UI? (I'm rusty but thought/imagined DLLs were run after the UISequence)


*>  Also I don't think it's possible to detect other users per-user
installed products *

Does that apply only to FindRelatedProducts, or also apply to a custom
action calling MsiGetProductInfoEx ?

Many thanks to all!
