Help running a PC game

Hi, i have 'call of duty 2' on my hard drive, and when i try to open in it says in msdos, not enough memory, it is an application file type????? does this make sense?.

 

What operating system do you have?
And What are the specs of your computer

 

windows XP, and it laptop, 60gig HD, 1.6gh 504ram....

 

Try restarting your computer.
Looks like you could use some more ram, 504 isn't very much for gaming.

 

it says the file type is application. so i cant explore the file to see other files inside it or nothing
it just is a white box and is 600mb size. but tries to open in msdos wen i click on it

 

I think a better video card would help but you can't upgrade those in most laptops so I am sorry but I don't know what to tell you.
