Does the Geogrid Viewer run on Windows Vista?
Geogrid Viewer 6.3 can be updated to Version 6.6 with the program update on the download page. Version 6.6 has been released for Windows Vista. The prerequisites for this are an OpenGL-capable graphics card and up-to-date drivers. The drivers pre-installed by default with the Windows Vista operating system are only DirectX-capable. Drivers that support at least OpenGL 1.3 then need to be downloaded from the website of the system or graphics card manufacturer and installed on the computer. If there is no OpenGL-capable driver on the system, there can be problems with the Dynamic Perspectival View (DPV) in Geogrid Viewer 3.2.
