- U must do clean install 

- Before starting setup launch RegGen and chosse patch setup to install with Email then start installation.

- After installation is done, untick launch Daemon Tools, if opened automatically, close it completely.

- If you are running Windows 7, Windows 8 or Windows 8.1, run Reg Gen as "Admin" from desktop or program directory, choose Ultra and save license. It should specifiy registered, close Reg Gen. Disable internet conenction before opening Damon Tools or block in firewall for your own good.

- If you're running Windows 10+, which I had tested on Windows 10 Pro 1703 Creators Update, you MUST copy Reg Gen to installation directory and you MUST run it as Admin importantly, otherwise it gives pattern not found error.

- Thanks @ ADMIN@CRACK for the RegGen.
