During the UI sequence I have a CA that runs an installscript function. This function sets a property value accourding to some conditions. I use the method MsiSetProperty to do that and right after that I check the property value with MsiGetProperty to make sure everything's fine - and it is OK.
Later on in the Execute sequence I get the CustomActionData property (using again a CA) and parse it in a list. Thus I can read several properties at once. Among these several properties that I parse is the one I set up in the UI sequence. UNFORTUNATELY the property has its default value and NOT the one I already wrote with MsiSetProperty, although I checked it right after setting it up and it was OK :confused:
