I have an msi application,there is 10 files.Iam not set key path for two files can we repair that two files?
Only by forcing a repair from control panel.
Self healing will not be triggered by a missing file if the file is not a key path of a component.
If your issue has been solved, please use the "Mark as Solution" link on the most relevant thread.
1. Manual Repair through ARP, as said by @EDT
2. msiexec /fa [ProductCode]
