If you must download it, use a dedicated AVEVA support account, prepare a Windows 7 VM beforehand, and apply the latest InTouch 2014 R2 Patch 03 (available via the same portal) immediately after install. Do not expect a pleasant out-of-the-box experience, but for running a decades-old bottling line or power panel, it will get the job done.
Only under contractual duress. For everyone else: emulate, virtualize, or upgrade.
Overall Rating: ⭐⭐⭐☆☆ (3/5 – Functional but dated and access-restricted)
