Signing a QuickPatch Package
Project: This information applies to QuickPatch projects.
Windows Installer 3.0 and later enables you to create patches that can be installed by nonadministrators.
Non-administrator QuickPatch packages can be used if strict criteria are met. For
example, the base installation that the patch will update must include the certificate that will be used to
sign the patch package. To learn about the other criteria that must be met, see Non-Administrator
Patches.
Task To sign a patch package:
1. In the View List under Define Patch Settings, click General Information.
2. In the General Information explorer, click Build Settings.
3. Click the Digital Signature tab.
4. Select the Sign the patch package check box.
5. Configure the digital signature settings.
Password-Protecting a QuickPatch Package
Project: This information applies to QuickPatch projects.
For added security, you can password-protect your QuickPatch package. When you password-protect
your QuickPatch package, any end user who wants to apply your QuickPatch must enter a case-sensitive
password to launch your update.
Task To password-protect a QuickPatch package:
1. In the View List under Define Patch Settings, click General Information.
2. In the General Information explorer, click Build Settings.
3. Click the Advanced tab.
4. In the Password Protect Launcher setting, select Yes.
