Preparing Installations for Non-Administrator Patches
Windows Installer 3.0 and later enables you to create patches that can be installed by nonadministrators.
Non-administrator patches 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 prepare a base installation that can later be updated by non-administrator QuickPatch packages:
1. In the View List under Prepare for Releases, click Releases.
2. In the Builds explorer, select the media type that you want to create or modify.
3. Click the Signing tab.
4. Specify the digital signature information.
InstallShield adds the necessary information to the MsiDigitalCertificate table and the
MsiPatchCertificate table. This enables you to create QuickPatch packages that can be installed by
non-administrators.
