Viewing and Setting Properties in the MSI Debugger
InstallShield 2020
When the debugger stops at a breakpoint or at an action or dialog because you are stepping through the installation, you can view Windows Installer properties and change their values at run time in the Watch window or the Variable window.
The Variable Window
The Variable window displays every property in the database’s Property table—exposed in InstallShield through Property Manager View—and its current value.
To change a property’s value as the installation is running, edit the Property Value column.
If you do not see the Variable window, click Variable on the View menu.
The Watch Window
You can enter the name of any property in the Watch window to check its value at any point in the installation. For example, enter TARGETDIR in the name column to see what TARGETDIR resolves to at run time.
To change the property’s value as the installation is running, edit the Property Value column.
If you do not see the Watch window, click Watch on the View menu.
