virtual memory is not enough

What version of Windows are you using?
Nowadays, getting by with less than 1 GB RAM is pretty difficult, and most have at least 2 GB as the bare minimum.
What processor are you using?

Save your work and reboot your computer and try again.
If you still run into that problem, go to Start-Run-msconfig-Enter
Go to the Startup tab and uncheck anything you know you don't want to start when Windows loads, such as Quicktime and other trash.
If you aren't absolutely sure you don't need it, leave it alone.
Then reboot and try again.
If for some reason you want it back, go to the Startup tab again, check the box, and reboot again. It will run again.
