Ok, so you've just added memory to that aging Windows XP computer you have and now when you try to run that faithful old application, Adobe Photoshop LE let's say, you get some error message indicating you don't have enough memory to run the application. How can this be? You just ADDED memory. You quickly go to "My Computer" and confirm the machines sees all that new memory. Maybe some of new memory is faulty, so you run a memory diagnostics program only to find out, the memory is fine. So you now resort to Google. Surely someone else has had this problem. after a few hours of looking, you find that yep, lots of people have had this problem, but not a lot of solutions are put forth.
So here you go. Most personal computers are setup to let the operating system manage the virtual memory. This is the recommended setting. Virtual memory is space on the hard drive that is used when you have exhausted the available RAM in the system. However it appears that when memory is added to a windows xp pc, the operating system fixes the minimum and maximum virtual memory levels. For some reason this cause some programs like earlier version of Photoshop to bomb out with a "not enough memory" error.
To fix this problem, right click "My Computer" -> Properties -> Advanced -> Settings (under Performance) -> Advanced tab -> Change (under Virtual memory) Make sure the correct hard drive is selected and select "System Managed Size", click "Set" and back out. Re-boot the computer and test the application.
