Problem running an application in Windows in Parallels

Tried running my application in Windows after installing it, and was prompted with the message: "....detected there is a low amouont of system physical memory (24.3%) available which could lead to low system performance. ........."
What steps should i take to remedy this ? This is the only app that i am running in Windows.
