Determining the Run-Time Effects of a Patch

InstallShield 2016

You can use InstallShield MSI Diff to determine what Windows Installer will do with a given patch file and how that will affect the cached .msi package on a target system.

To determine the run-time effects of a patch:

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. InstallShield MSI Diff applies the patch to the database that is open.
6. Examine the changes.

If you want to apply a series of patches to an .msi package, you can repeat steps 4 and 5 for each patch.

Tip • Note that InstallShield MSI Diff also lets you apply a series of multiple transforms and patches to an .msi package, and see the changes in the resulting .msi database.

To learn how to apply a transform to an .msi package, see Determining the Changes that a Transform (.mst File) Makes.
