stuff...

Subject: [WiX-users] When does the Registry key/value get deleted during 
Uninstall

Hi,
There is a tricky problem bother me these days. I don't understand why the 
certain Registry key/value got removed before my uninstall custom action is 
called.
we have a custom action scheduled after ProcessComponents, but before 
RemoveRegistryValues:
InstallValidate
InstallInitialize
ProcessComponents
MyCA
....
RemoveRegistryValues

we also defined Registry key/value in the MSI's Registry table. so it will get 
created and removed during install and uninstall.
MyCA is a deferred uninstall custom action will read from that Registry Key.

but during our testing, when MyCA is get called,  the Registry key is already 
deleted.
Does ProcessComponents will delete the registry key?? I thought 
RemoveRegistryValues will do that job.


thanks,
William L.
