Once you've installed the software, see the Quick Start Guide
1) Download the installation file. Locate the file and run your normal anti-virus scan on it. Once you're happy it's free of viruses, run the installation file. You should see something like this:
Click Yes to proceed or No to cancel.
Instead of the above, Windows may throw up a warning similar to the one below:
At this point you either trust me (and my company, Spacejock Software) and click 'Yes', or you click 'No' and delete the installer. That's up to you - just bear in mind I set up this website over twenty years ago, and if I was offering dodgy software someone would have closed it down by now, wouldn't they? I'm also an author with almost thirty novels in print, and my reputation matters to me!
2) Follow the prompts to set it up. (The defaults are fine)
3) Locate the Spacejock Software entry in your start menu. The program you just installed will have an entry there. Click the program icon to run it.
