Now it's been renamed as OpenScape Desktop Client. V3.2 R2.0.2 (32.2.0.0002) It will run on Windows 7. I won't say "without any issues", as it appears to be quite picky. I had it running on my desktop fine for a month or so. Now it just won't launch. As far as the user interface is concerned-- it's completely different than the OC130 in almost every aspect. It'll take some getting used to, that's for sure.
