When you click OK Researcher will eventually connect to the camera after about 10 seconds. Is this serious, or can I ignore?

Researcher installs and uses the 2.1.3 Pleora libraries and drivers. If you install RTools 2.2 on the same computer you will need to install the Pleora 2.2.0 libraries and drivers. If you configure your network adapter to use the 2.2.0 Pleora High Performance driver the error message will start to appear. It is not clear at this point if the error is generated by Researcher or Pleora.

In any event, the 2.2.0 High Performance driver seems to be compatible with Researcher and the 2.1.3 libraries. Just ignore the error message and click "OK". The good thing is that the 2.2.0 High perf driver is compatible with many more NIC cards than 2.1.3 so you may be able to use the high performance driver with Researcher where with the older driver you could not.
