1. Use an immediate custom action to generate the "scrambled" registry value into a property (C++ or .NET via DTF). 2. Encode the current ProductVersion property into that value as well. If the value already exists in the registry (use a property initialized via RegSearch) verify if the embedded ProductVersion matches the current ProductVersion (if they match, keep the value already in the registry, if they don't, generate a new value based on the current date). Or some variation on the theme...
