Spacejock Software Installer

Because all my programs share the same basic set of files, I've written a program called the Spacejock Install center to make your life easier (and save both of us some bandwidth). You only have to download the Install Centre once - after installation, you can use the simple interface to retrieve and install any of my programs. If you're running a firewall, you will need to give the Install Center access to port 80 (internet) so that it can retrieve information about the programs available and also so that it can download the programs themselves.

Primary download site: Installer Full Install (3mb)

1) Download the installation file. Internet Explorer users are forced into a series of pointless* security warnings which look something like this:

Cannot be verified

Just click Save. You'll get another warning (this one with a nice friendly red X):

Cannot be verified

Click View Downloads:

Cannot be verified

Once the downloads folder is open, locate the downloaded file and run your normal anti-virus scan on it. Once you're happy it's free of viruses, run the installation file. On Windows 7 or later, you must right-click the installer and choose 'Run as Administrator'. Now Windows will probably throw up another 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 ten years ago, and if I was offering dodgy software someone would have closed it down by now, wouldn't they?

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.

System Requirements:
Visual Basic 6 runtimes (included in the installer)
Any version of Windows, right back to Win 95. (e.g. Win95, Win98, Win2K, XP, Vista, etc)

Hardware: if you're running Windows, you can run my programs.

Vista users should read these additional comments.

Linux users: This app installs and run under Wine, at least on Ubuntu 7.10
