Hi, I had problems with installation on Win 8.1 64bit (AMD processor). The installation process does not end. It stops at the dialog where it informs the user to wait, writing values in the register is run. I waited hours. I repetead the installation as administrator rights and disabled antivirus. The problem returns. How can I fix the problem? I downloaded the version 64 of DrawSight and tried to install the stand-alone license to try the product. Thank You.
