Are there any guides that will help beginners make themes?

[I am new here so I don't know what to do most of the time.]

Hello, I have recently purchased and downloaded Windows Visual Style Builder and I am new here so I don't know what to do most of the time. So basically, after I had tried to open the software multiple times, it would not open. I may be doing something wrong since I am opening the software from C:\Program Files (x86)\AveApps\Windows Style Builder. Is there any way I can fix this problem?
