According to the official website of the developer, the program mentioned isn't among the available products. This could mean that the program was discontinued. If this is the case, it will no longer receive updates, so in order to use it on Windows 8, you should use the Compatibility Troubleshooter. This can be found by searching for it in the Start menu. However, the best thing that you can do is to contact the developer for further support in this matter. Use the site mentioned above to do that.
