Hi,

you need a URI protocol for it in the Windows-installation. E.g. "mailto:mail@mail.com" opens the known mailprogram in windows (if any). If you define that you can call e.g. "cacheterm://namespace" that would start the Caché Terminal with defined Namespace.

An example is here: https://dev.to/avinash_tare/how-to-create-own-url-protocol-in-windows-4…

If this is the solution you want, can't tell. It would be better to have Webterminal installed (IRIS).
