Target Manager perspective error

I get the following when opening the Target MAnagement perspective on a fresh install of DS:

Anybody seen this?

Solved it!

I did not have the USB-Serial Port driver installed on my new laptop. Since this machine doesn’t have any hard serial ports, that meant Developer Studio couldn’t find any serial ports. Apparently this caused a big problem.

I installed the driver for my USB-Serial port adapter, restarted Developer Studio, and everything functioned normally.

Sierra Devs: This should be entered as a UI bug. If Developer Studio can’t locate any serial ports, it should probably warn the user instead. The Null Pointer Exception traces made it appear the installation was corrupt.

Already known issue: DS will indeed behave quite bad if there is no serial port at all…
Planned for fix in next release.

Just as an aside:

I know laptops haven’t had external COM ports for years, but they’ve generally had an internal modem that appears as a COM port - is that now also on the way out?

(wouldn’t surprise me - who uses dial-up modems these days?!)

Yeah, this new laptop lacks a modem (it still has the plastic cutout where one would potentially have been installed). I guess the days of the modem are officially behind us.
