If you are the author of the MSI, then why not set the condition up properly in the first place? You can condition your actions based on a property, and then in your immediate CA you can modify the value of your property so your install takes the appropriate action.

I am looking for a way to open the msi database, check and see if a specific action exists in the InstallExecuteSequence table, and if it exists to modify the Condition statement related to that action. I have been considering doing this either at compile time but am concerned about the fact that the order of processing nodes is not something which should be assumed. I am also looking at doing it in an immediate action but do not know if it is possible to change the Condition statement of an existing action at runtime. 1) Is it possible to change the Condition string of an entry in InstallExecuteSequence using an immediate CA? 2) In either case above, if one is possible, can you suggest any example code (or relevant functions) in the wix src (or elsewhere) which might be useful to study. (I think I see how to open the db but it is the issue of changing it that am researching. I read about adding a temporary record, but I am looking for a way to modify when an existing record is fired.)
