I have to admit to being confused! Looking at the built in WiX custom actions I see code like this in their wixlibs:
<CustomAction Id="InstallSqlData" BinaryKey="ScaSchedule2" DllEntry="InstallSqlData" Execute="immediate" Return="check" /> <CustomAction Id="UninstallSqlData" BinaryKey="ScaSchedule2" DllEntry="UninstallSqlData" Execute="immediate" Return="check" /> <InstallExecuteSequence> <Custom Action="UninstallSqlData" Before="RemoveFiles" Overridable="yes">NOT SKIPUNINSTALLSQLDATA AND VersionNT > 400</Custom> <Custom Action="InstallSqlData" After="InstallFiles" Overridable="yes">NOT SKIPINSTALLSQLDATA AND VersionNT > 400</Custom> </InstallExecuteSequence> Where is the detection or conditional calls in that? In most cases this seems to end up calling the same code but with a true/false code indicating install/uninstall.

To detect if the product is being uninstalled you need to check the REMOVE property: http://msdn.microsoft.com/en-us/library/aa371194.aspx. But of course you won't be able to access that from a CA running in deferred/rollback/commit mode. Typically, uninstall custom actions are conditionally scheduled in the sequence table using the REMOVE=ALL condition, so the CA would not need to check for uninstall mode via an API. -----Original Message----- From: Neil Sleightholm [mailto:n...@x2systems.com] Sent: Wednesday, February 18, 2009 11:59 PM To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] DTF - install, rollback and uninstall I took at look at that and couldn't figure out how you could tell it was being called during and uninstall. I am sure I am missing something obvious!
