Determining Whether a Patch Is Valid for an .msi Package
InstallShield 2020
You can use InstallShield MSI Diff to determine whether a patch is valid for a specific .msi package. InstallShield MSI Diff analyzes the internal transforms that are contained within the patch.
To determine whether a patch is valid for an .msi package:
| 1. | Open InstallShield MSI Diff. |
| 2. | On the File menu, click Open. The Open dialog box opens. |
| 3. | Select the .msi package, and then click Open. InstallShield MSI Diff opens the .msi database. |
| 4. | On the File menu, point to Patches, and then click Apply Patch. The Open dialog box opens. |
| 5. | Select the patch (.msp file), and then click Open. |
If the patch applies to the selected .msi database, InstallShield MSI Diff applies the patch to the database that is open. If the patch is not applicable, InstallShield MSI Diff displays a message box to inform you that the patch is not valid for the selected database.
