I believe so.

Custom action are in MSI database which is transformed before the 
install/uninstall (really repair in the case of the patch) starts running 
custom actions. So during patch install you get patched actions executing. 
During uninstall you get unpatched action or no action executing because that 
is the state of the database before it was transformed by the patch. Now it got 
transformed back and it lost added custom actions.

Subject: [WiX-users] Question regarding the behaviour of custom actions during 
patch uninstall


Hi,

I've scenario where I've added a couple of custom actions as part of the patch 
and sequenced them in during install as well as the uninstall. Now during patch 
install the custom actions are executed properly but during patch uninstall 
none of the patched custom actions are executed. Is this by design?

Thanks
Anurag
