Yes, Schloss has the answer for registration. install the program, copy ALL of the license info on the page taken to by “Registration file for above” (in red) to the file vopt9reg.txt… make one if it doesn’t exist in the Vopt9 program file and when you restart VOPT, it will say that it is Registered, compliments of the author. I was also confused when the instructions said to double click on the file, vopt9reg.txt and then click Register… I had no file named vopt9reg.txt
