InstallShield 2014 Express Edition
The Windows Installer service uses several file overwrite rules, by default, to determine whether a file included in an upgrade should overwrite a file that already exists on the target system. The rules apply when the REINSTALLMODE property uses the o setting to install over older files on the target system. To change this behavior, you can replace the o option with one of the following values:
| • | p—Reinstall only if there is no equivalent file on the target system. |
| • | e—Reinstall if the file is missing or if it is an earlier or equal version. |
| • | d—Reinstall if file is missing or different. |
| • | a—Reinstall all files, regardless of version. |
Note that the setting for REINSTALLMODE applies to all of the features being installed; it cannot be set for an individual feature. In addition, setting REINSTALLMODE to include a will likely cause prompts for the original installation source during the application of a patch.
