I am trying to virtualize some software that writes user preferences to the registry. This would be similar to signature or some other setting for a MS office product. I create the preferences when the layer is activated. I can deactivate it and the prefences will be there when I reactivate it. However when I reset the preferences are gone. I know this is by design, However is there a way that I can exclude these preferences/registry entries from being removed if the layer is reset. Basically I am wondering is there a way to manually set a registry key and all the entries it contains are permenant(actually written to the registry)? Something like HKEY_Local_Machine\software\microsoft\word, so I would like to keep the word key and all the registry entries it contains. I have spent time in the Edit Advanced Layer Properties Registry section trying out the Write and the Read sections and I have had no luck. We are looking at this also for an upgrade scenario. Preferences you set in version 1 will be saved when the software is upgraded to version 2. I hope this makes some sense. I really appreciate all your help. Thank you very much.
