Nothing to display. This application is uninstalled using Wi

Error message

Nothing to display. This application is uninstalled using Windows Installer (MsiExec).

What it means

ExtractFileInfo found that the uninstaller file does not exist on disk and the entry's UninstallerKind is Msiexec. MSI uninstallers run through the Windows Installer service (msiexec.exe) rather than a standalone executable, so there is no on-disk file metadata to display. The NotSupportedException message comes from PropertiesWindow_Table_ErrorMsi.

Solutions

1. Use the Registry or Certificate tab for MSI-typed entries.
2. Re-cache the MSI package if you genuinely need file metadata.
3. Treat MSI entries as having no file-info tab and default to Overview.

if (entry.UninstallerKind == UninstallerType.Msiexec && !File.Exists(entry.UninstallerFullFilename))
    /* skip File info tab for MSI entries */

When it happens

Trigger: Opening the File info tab for an MSI-installed application whose cached MSI/uninstaller is gone; a system-component MSI entry.

Common situations: MSI apps whose cached .msi was deleted by disk cleanup; Windows component-store MSI entries.
