1. Update your anti-virus software and run a virus check on your system. Some runtime errors can be caused by computer viruses.
2. Disable third-party, pop-up blockers on Internet Explorer. Internet Explorer running under XP can prevent frames and table some websites from opening, causing runtime errors.

3. Close all applications except for the ones you are currently using. Sometimes, incompatibility issues will cause runtime errors. You can cut down on your odds of getting a runtime error if you only keep open those programs that you are actually using.
4. Check the program manufacturer's site for updates or fixes. Manufacturers often issue fixes for runtime errors.
