I do work for Ranorex and I would like to join the conversation if you don't mind
To sum up the history:
Ranorex did support Edge until the Windows 10 Anniversary Update (August 2, 2016), with which Microsoft ceased support for the COM interface in Edge that Ranorex relied on. At the release of the Anniversary Update we were already in contact with Microsoft and were told that this is a bug that will be fixed. Three months later the issue was then closed as by design.
Anyway, we see the relevance of being able to test as many available browsers as possible, including Edge.
As a small teaser I can give you the following information:
Ranorex will shortly support Edge and Safari (on Mac) again with the upcoming Ranorex 7.0 release at the end of Q1 2017.
And thank you everyone for your input!
Regards,
Alex
