Chapter 9: Configuring the Target System
Using Environment Variables
InstallShield removes the corresponding row from the ODBC Attributes & Properties pane.
Using Environment Variables
Environment variables are name and value pairs that can be set on the target system with your
installation and can be accessed by your application and by other running programs. Environment
variables are stored in the registry.
In the Environment Variables view, you can create new environment variables, modify the values of
existing variables, and remove variables. The environment variable creation, modification, or removal
takes place when your application is installed—depending on the properties that you set for the
environment variable when you added it to your project.
Setting Environment Variables
Task To create a new environment variable or modify the value of an existing environment variable:
1. Open the Environment Variables view.
2. Right-click the Environment Variables explorer and click Add Environment Variable.
InstallShield adds a variable with the name NewEnvironmentn (where n is a successive number).
3. Type the name of the variable that you want to modify, remove, or create.
4. Edit the properties of the environment variable.
Per-User vs. Per-Machine Installations
Two Windows Installer properties, along with the current user’s privileges, affect where the
configuration information such as your product’s shortcuts and registry entries are stored on a target
machine—to the All Users profile or the current user’s profile:
• ALLUSERS determines where the configuration information is stored.
• MSIINSTALLPERUSER indicates that the Windows Installer should install the package for only the
current user.
The MSIINSTALLPERUSER property is available with Windows Installer 5 and on Windows 7 or
Windows Server 2008 R2. Earlier versions of Windows Installer and Windows ignore this property.
ALLUSERS, MSIINSTALLPERUSER, and Windows 7 or Windows Server 2008 R2
If the ALLUSERS property is set to 2 and MSIINSTALLPERUSER is set to 1, the Windows Installer
performs a per-user installation.
