Modify the in private recording setting
The in private mode set in IE by default for SP 15 onwards is interfering with the recording on some environments which don't allow in private mode to be used. When this happens the in private argument needs to be removed or IE wont open. It would be beneficial to either remove this, or have this as a separate IE profile so users could select whether they wanted to use in private or not. Alternatively if the installer could check if the gpo which disables this functionality is in place and install the appropriate application profile.
