From the developer:
Sometimes, the hardware provides everything that Topicscape needs, but the driver doesn't. glVersion (called GLInfo when installed) can check for some know problems, but not all. There is a compatibility test that can dig a little deeper and can be used if you have some uncertainty, and a way of providing a text file of technical information about your graphics hardware and driver that can be sent to us if you need assistance.
You may want to check out more software, such as AMUST Registry Cleaner, Appget or Ashampoo Magical UnInstall, which might be related to GLInfo.
