Software Deployment

...and the table's name doesn't provide the teeniest clue-ette?

Registry adds registry keys, values and /or data. It can also be used to delete keys and their underlying values and data. It is read by the WriteRegistryValues and RemoveRegistryValues actions.

RemoveRegistry deletes registry keys, values and/or data. It cannot be used to add. It is read by the RemoveRegistryValues action.

OK.. Got it...!!!

I added couple of entries to RemoveRegistry table. These are the entries that get created during application execution and NOT during installation (by reading them from Registry table).

Now the problem I am facing is,

1. Any such key that was created during installation gets removed only at the time of next Install and NOT during the current un-installation.
2. If condition is specified for RemoveRegistryValues action as REMOVE="ALL" then the specified key doesn't get deleted at all; neither during installation nor during un-installation.

F1 please!!!

Check which component are you referencing in your Removefile table, reference a component which holds your main exe file(or any of your component which hold a PE file- just to be sure that they get uninstalled when the app is uninstalled) and make sure that component is getting uninstalled first, then there should be no reason for your registry not getting uinstalled.....provided you have given the right registry key etc

Don't condition that action: it's perfectly valid for it to execute during installation and uninstallation. As stated, make sure the component containing your registry removal is "attached" to a feature which will be uninstalled.

check the last column of the table.

I am not pretty much sure about that..
Let me confirm it from my brother then I will reply you with the authenticated source....

this I think is.. well... wrong, or to be precise, incomplete. I had a bit of a discussion with Ian on this topic recently (in this thread), so here's how I decided they work:

Registry Table : Write Reg Keys / values during INSTALL, uninstall Reg Keys /Values during UNINSTALL
RemoveRegistry Table: Remove Reg Keys / Values during INSTALL (and uninstall? <- not sure)

RemoveRegistry Table: Remove Reg Keys / Values during INSTALL (and uninstall? <- not sure) Well, The RemoveRegistryValues action (which by default isn't conditioned) reads the RemoveRegistry table so unless a condition is added, it'll run during install and uninstall.
