Runtime error 203 is a problem you are probably unfortunate enough to have experienced, if you’re reading this article. Don’t worry–it probably doesn’t spell immanent disaster for your computer. At least not yet it doesn’t.
Runtime error 203 may simply stem from a problem with the particular program you’re running. Nevertheless, it might also say something about your system’s integrity as a whole. Read below to find out information about its symptoms, causes, and cures.
Runtime Error 203 Symptoms
- You receive a message stating, “Your computer is low on memory, save your documents and close all programs.” If you don’t close everything up, it’s very likely that you’ll get an error message and your computer will slow down considerably. (Your computer was probably already running slower than usual.)
- Your computer slows down right before you receive the error message. This is typical of many runtime errors. This is not unusual, so it doesn’t mean that your problem necessarily originates from malicious software like viruses (although they could be a factor).
- You get the runtime error 203 message, then whatever software you were running at the time shuts down. This can be highly frustrating. When the problem is this or the above, however, you may get off easy because it’s probably just a problem with the software. However, you may also have a problem with your registry.
- Your computer displays the “Runtime Error 203″ message, then crashes. This is a great big red flag out of nowhere. If this happens, then it’s seriously time to think about uninstalling the program, then running anti-virus software and a registry scan.
Where do these memory problems comes from?
Runtime error 203 is typically a memory-related problem and can come from a variety of sources.
- You have a copy of the test or beta version of certain software. You may have gotten the program by mistake, or downloaded it from a torrent site. Unless you bought the program directly from a merchant, there’s a good chance you have a beta version. There’s also a good chance that:
- You have spyware on your computer. This error usually comes from too little memory being available to complete the current tasks on your computer. You’ll do yourself a favor if you run a check for viruses and spyware on your computer.
- You have registry errors. Most computers do. At the very least, a large amount of files is left over from software updates and bad uninstalls.
If you’ve got (or have ever had) spyware or viruses on your computer, then they have probably left behind files in the registry that may be slowing your computer down. Run a free scan for runtime error 203 and keep your registry in shape.

Have you ever tried using a public PC? Some of you might probably answer in the negative. Indeed, going to Internet cafés to surf the Web is starting to become unfashionable these days as portable computers continue to get cheaper.
