Codes in deferred custom action cannot directly access MSI database.
In the function, you can only read "CustomActionData" property, of
which value is set as the name of the custom action.
For example, to transfer the data to the deferred custom action named
"MyDeferredCustomAction", you have to set the property
"MyDeferredCustomAction" by defining it in the MSI Property table or
using immediate custom actions. And then in your deferred custom
action code, you use "MsiGetProperty(_T("CustomActionData"), ...) to
retrieve the value.
See this: http://msdn2.microsoft.com/en-us/library/aa370543.aspx
In well-coded custom actions where deferred custom actions are
required, we only schedule the immediate custom actions in the
InstallExecutionSequence table, and in an immediate custom action
("MyImmediateCustomAction") , we access the MSI table and set
"MyDeferredCustomAction" property appropriately and call
DoMsiAction("MyDeferredCustomAction"). As MSI properties only can be
strings, you may have to use parsers or use binary-to-text
encoder/decoder (e.g. binhex, base64 or ascii85).
Hope this helps.
