If you are getting errors and you're running an older operating system (Windows 9x/NT), then the reason is most likely to do with an incompatibility between Rocscience software and older operating system files. Rocscience software requires up to date operating system files in order to run properly. As a rule, Rocscience does NOT change or alter your operating system files and puts the onus on you to maintain up to date operating system software.
This problem can easily be fixed by downloading the latest Microsoft system file updater from our website: http://www.rocscience.com/downloads/general/vcredist.exe
Download the file by clicking on the above link. Save the vcredist.exe file to your computer and then run it. Follow the directions.
Note: It is always advisable to make a backup before installing software that modifies system files.
The program requires that the computer's graphics card has support for OpenGL for the visualization of the three-dimensional geometry. The most common reason for the improper display of the wedge geometry or crashing of the program while trying to view the three-dimensional geometry, is an incompatibility with the graphics card (display adapter) and its support for OpenGL. If your graphics card does not support OpenGL (most do), the program will not work, so check with your graphics card manufacturer to make sure that your card supports OpenGL. Also, if the graphics card driver is old and has bugs with its OpenGL driver, then the program will have problems. Go to the website of your graphics card manufacturer and make sure you have the latest driver for your graphics card.
Another thing to try is changing the colour depth of the current video card settings. Try changing to 24 bit colour or 16 bit. Some cards have problems with their OpenGL support at higher colour depths.
Also try the program on a different computer.
