MSI engine surely detects every file in use which needs replacing. It only shows the associated application, not the affected files, though.
Maybe MSI should provide some properties or information for such files in use. But as I can find none, we may have to deal with creating a custom action to achieve what you want. * Create an immediate custom action to detect files in use which needs replacing. 1. For each row in File table, get the file key and test [#filekey] is not null after CostFinalize action. Those files (#filekey is target path) are being installed in your local system. 2. With those files, use CreateFile with no file sharing mode and check for errors, if the file handle cannot be obtained, it is in use by other applications. List of such files can be shown use MsiProcessMessage. Add "Ignore" also in your dialog, as there can be some cases where it is not feasible to close the application. As this is an immediate custom action, there are still some possibilities that files are locked during the lapse between the detection and copy script execution. But as MSI schedule a reboot in that case, it is okay. (Not 100% prevention is possible). Maybe there is a better way than this, which I do not know yet.

I need to show dialog with locked file name. Information about running application is not obligatory.
