Icon Command Description
Setting Install/Uninstall Behavior for Registry Keys
Chapter 9: Configuring the Target System
Editing the Registry
Install if absent,
Uninstall if present
(*) Project: This registry flag type is available in Express projects.
This option is similar to the default behavior (the Automatic registry flag), with one
exception. For the Automatic registry flag, if the key is not empty during
uninstallation, it is not removed. For the Install if absent, Uninstall if present (*)
flag, if the registry key is present during uninstallation, the key is removed,
regardless of whether its subkeys or values remain.
In InstallShield, installation and uninstallation behavior for registry entries is set at the subkey level.
Task To set the install/uninstall behavior for a registry key:
1. In the View List under Configure the Target System, click Registry.
2. In the Feature list, select the feature that corresponds to the registry key whose behavior you are
setting.
3. In the Destination computer’s Registry view pane, right-click the registry key and then click
the appropriate behavior.
Install/Uninstall Behavior Options
In InstallShield, installation and uninstallation behavior is set at the subkey level. All values beneath the
key must have the same installation and uninstallation behavior. For a list of available options, see
Registry Flags.
Handling Registry Entries for a Per-User Installation
Since the current user may not have sufficient privileges for modifying keys under
HKEY_LOCAL_MACHINE, you may need to write the entries under HKEY_CURRENT_USER.
When you select HKEY_USER_SELECTABLE in the Registry view, the entries are created under the
appropriate registry hive, according to the type of installation and the user’s access rights:
• In a per-user installation, meaning that the installation is being run by someone with user-level
access privileges, these entries would be made under HKEY_CURRENT_USER.
• In a per-machine installation, meaning that ALLUSERS is not null and that the user is an
administrator, the entries would be written under HKEY_LOCAL_MACHINE.
