    It seems that you are using AR6 on Win10 and AR6 is not compatible with Win10. Also, AR6 is a legacy product. It is out of development mode from a long time ago and we don’t support it.

    I suggest you to upgrade to our latest version i.e AR14. For more information, you can refer the following link:

    Also, you can download the trial version of AR14 from the following link:

    Thanks, Mohit
