Silent install tip

For Topaz Photo AI from Topaz Labs, deploy silently using the MSI installer with the command: msiexec /i TopazPhotoAI-x.x.x.msi /qn /lv install.log, where /qn suppresses the UI and /lv generates a verbose log file for troubleshooting. This approach ensures reliable, unattended installation suitable for enterprise scripts via tools like SCCM or PDQ Deploy. During initial runs, temporarily disable antivirus to avoid model download blocks.
