This application has failed to start because AcGe16.dll missing

Hi there,
I have this error when I want to open 3ds max. I reinstalled the program again because I had to reinstall my Windows XP. My previous Windows were 7 and the program worked just fine, but I don’t like the OS. Can anyone help me to run this program on Windows XP ? Should I install Windows 7 again?
Thanks experts!
