I have 4 addons that IE says are related, 3 of which have the same version #. It says, "Control name is not available".
Web Test Recorder 10.0, version 220.127.116.116.0
WebUI TestStudio Recorder, same version
WebAii Test Execution Extension, same version.
I also have something called Discuss, that wants to be enabled at the same time.
The only other enabled addons are Silverlight and Flash.
I tried enabling all 3 addons with the same version # (18.104.22.1686.0), and only enabling the two you mentioned (WebUI and WebAii).
In all cases the browser starts up when you press record, but a popup starts up soon afterwards saying that the browser has stopped working. In fact, that's been happening a fair amount when doing normal activities since installing WebUI Test Studio yesterday. it seems to go away when I disable all of these related addons.
Yes, I installed and am running this in an account in the admin group for my machine.
