Apparently you couldn’t solve the problem yet, at least I didn’t see any feedback. Please, tell if you need more help?

Sorry, forgot to insert the attachment, and cannot do it in the original comment.

You need to edit the AdobCaptivate.ini file which you can find in the installation folder. You need administrator rights. Make a copy of that file to another location and edit the line 16 §see screenshot). Save the edited file, rename the original file in the installation folder because you’ll need to reset it to have a working editing environment. Replace it by the edited file.

Pesronally I am not able to record because everything becomes too tiny. I keep an old system for recording with set to a non-retina resolution to avoid this workaround.
