"Native Access" download 'License Agreement' won't accept an input that would allow it to function.

Thank you very much for the screenshot. I personally needed to be sure that we were not looking at some graphical problem with some part outside of visible screen area (I have had that a lot myself).

If after clicking the EULA area then you can not use scroll wheel on mouse to scroll on neither vertical scroll bar or inside the EULA text area and it does not help either clicking inside EULA text area and pressing 'down-arrow' on keyboard then all I can come up with would be to see if clicking the Tab (Tabulator) keyboard key to the left will somehow change Windows' focus and allow you to use 'down arrow' to scroll (that is done by pressing Tab key once then check Windows' focus and then press Tab key again and then re-check focus)(on mouse less navigation then Tab key is used for Windows' interface focus change !).

Else there is two things that springs to mind as possible reasons , one is the classical user access permission problem with interception by Windows' or added security measures which could make something like this lock up.

The other may sound a bit far fetched but could still be a possible reason. I see that you are using a generation 12 Intel i7 CPU . There has been seen program 'execution' problems of different kinds using a CPU with both P and E cores (PDF : P and E cores) and while it is maybe only a remote possibility then it is still a possible reason in a case like this. Me airing remote possibilities usually only earns me down-votes and negativity in this forum (even an otherwise esteemed forum member recently down-voted when I suggested trying to change a monitor refresh rate where I thought it an only very remotely possible reason) but I will still put this forward as a possible reason. In any case you always need to make sure that you have all the correct intel drivers from manufacturer installed (possibly including Intel Thread Director ? and what not ?)(last time I installed a Generation 13 i7 CPU and MB based computer and installed the drivers I had a really hard time with amount of stuff that needed installing from motherboard manufacturers site) and that Windows is up to date. But when we are looking at a never seen before problem I think that it needs mentioning. I have no real insight into the Windows drivers for stuff like that or into the technology behind or if the Native Access program even are executed using more cores or if so which in what cases so this is only me trying to make sense without enough insight !

Else as Mykejb points out then the only other viable option is N.I. N.A. support !
