ERROR_INSTALL_SUSPEND
ERROR_INSTALL_SUSPEND means that Windows Installer did not complete the operation. Treat the product state as incomplete until a supported continuation, repair, rollback, or uninstall has established a known state.
What to check
- Keep the installer log and identify the last action completed before the operation was suspended.
- Do not start a second installation that assumes the first transaction completed successfully.
- Use the product vendor’s documented recovery path rather than manually deleting installer files or registry entries.
