As you can see on the official web page, MATLAB 7.0 is an old version of the application which is compatible only with Windows XP, Windows 2000 and Windows NT 4.0. If you want to use it on your Windows 7 PC, you can try to download and install Windows XP Mode and install the application in this environment. Windows XP Mode makes it easy to install and run many applications compatible with Windows XP directly on a Windows 7 computer. Also, you can check the system requirements for all MATLAB versions on MathWorks website.
