For most folks it's not an issue, with the scarcity of serial (COM) ports on newer systems.

I just got the Vista Express Upgrade for my newish laptop. After I install it, I'll be happy to try loading RC3200 Setup (need to modify my NCF, anyway) to see if it runs. However, since the laptop doesn't have a serial port, I won't be able to test communication with the remote.

As far as an update, I wouldn't hold my breath. Marantz no longer sells the RC3200, and Philips stopped development a couple of years ago. The latest updates on Marantz's site carry dates from nearly two years ago (and I think the files may be older than that--I remember the dates changing, but the content staying the same).

If RC3200 Setup doesn't run under WinXP compatibility mode, you'll need to keep a legacy system around to update your remote. I still have a Win2K system that I use for remote updating.

Good luck.
