My "admin-image" style WiX test patches are failing to update the existing installation correctly. When using msiexec /lx, I get the following information related to patching "fi_executable.exe":
MSI (s) (88:E0) [12:32:41:716]: Baseline: Patch {E244BAC8-7E62-4406-889B-4B67A4EA7369} modified fi_executable.exe with full-file update.
MSI (s) (88:E0) [12:32:41:716]: Baseline: First patch for fi_executable.exe, saving native info.
MSI (s) (88:E0) [12:32:41:716]: Baseline: fi_executable.exe version for baseline at patch Native: 6.0.5803.11, 1033, 53840.

MSI (s) (88:E0) [12:32:41:763]: Native File: fi_executable.exe ValData: 6.0.5803.11 1033 53840
...
MSI (s) (88:E0) [12:32:42:543]: The file represented by File table key 'fi_executable.exe' has no eligible binary patches
So even though the version number is changing, and Windows Installer notes that the patch modifies the file, Windows Installer is not recognizing that there should be an update to the executable.
Why?
回答1:
Have you tested the upgrade with complete MSI files first before trying with the patch? Patching is just a delivery mechanism for upgrades packaged in a more compressed fashion, if the full MSI upgrade doesn't work, neither will the patch.
回答2:
Try to install your patch with this command line:
msiexec /p patch.msp /qb REINSTALL=ALL REINSTALLMODE=omusa
Without these additional parameters, my patch failed to install correctly: it didn't update any files.
