Windows Vista hasn't changed the world after all, and compatibility issues have been a major concern. But it's often quite simple to get around the conflicts.
1. Vista’s graphics engine is one element guilty of causing compatibility conflicts. Sometimes it will stop programs from installing but, usually, you won’t find out there’s a problem until after the installation is complete. If you’re prompted to check for updates online, this will often rectify the problem.
2. The Aero interface can also cause problems, preventing some older programs from displaying correctly. However, if you can install the application and launch it then Vista will deal with the problem automatically, switching to the Vista Basic (non-Aero) interface while the program runs.
3. If the problems are more complex, Vista’s Program Compatibility wizard will usually provide a fix – with the exception of low-level utilities, such as antivirus software. Open the Control Panel and select the Programs icon to access Compatibility mode. This deals with all aspects of running software on your PC.
