Hi
I have an installer where i change some registry keys in

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\0,
where i change some security settings from my computer, to run some activex scripts (using RegDBSetKeyValueEx)

When uninstalling, it deletes the keys and then i have some problems with IE security.
The problem is that when uninstalling it deletes everything the installer have set.


Is it possible that when uninstalling not to delete these keys ? (maybe leave it as they are or re-setting

their values as they werw before installing).

Thank  you

Hi,

InstallShield removes everything it created before. Unfortunately, it cannot distinguish between writing an entry anew and modifying an existing one. Thus it always removes the entry at uninstall time!

A solution: prior to modifying an existing entry check if it does already exist. If so:
- copy the entry with a different name (create a different entry). You may disable LOGGING during this function call.
- Now modify the original entry.

But don't forget to extend your uninstall routine OnUninstalling... to rename the copied entry back to the original name. If you put the rename function into OnUninstalled..., the entry will already have been deleted, so no renaming can take place! If you disabled LOGGING: delete the entry on your own.
