Access violation errors are often caused due to compatibility issues between the application and the operating system, lack of updates, bad installation, corrupted registry files. The first thing to do is to re-install the application, but before doing that I recommend to install CCleaner to clean up the registry left by the uninstaller. CCleaner will delete obsolete data. This is a vital step in a repairing operation. After you complete this step, you can proceed further to install the actual game. If you still encounter errors, you should contact the developer to clarify the point.
