How do you solve an 'insufficient memory to run the application' error in Windows XP?

Several possibilities:

1. Remove some of the applications that are already hanging around. You may just have some spybots or viruses that are running in background. You also may have some applications running that you don't necessarily need.

2. Add more memory. Memory is cheap and you can often double the memory of your computer with very little effort or expense. It's one of the easiest things that you can do.

3. Make sure XP is managing the virtual memory. You should set the sizing to auto so that XP can deal with it.
