Is anyone wanting to know how to have both 1.0 and 1.7
on their computer? Well first of all you need to find the activision folder on your com,
then in there should be a folder "Call Of Duty - Modern Warfare".
Copy everything in that folder, go back, make a new folder called 1.0.
Open it and paste everthing in there.
Once you have done that find the thing that says im3p-MP (something like that (I forgot what it is called)
and drag it to your desktop, then rename it to 1.0.
Ok now that you have got that done, you can use the patch updates ( you only need 1.6 and 1.7 patch updates)
once you have installed the updates you will be able to play 1.0 and 1.7.
Ok here is the link for the 1.6 patch update:

(this one is about 200mb so for people with slow download it might take awhile)
and here is the 1.7 update:

(when downloading make sure you go down to the Australian download).
I hope this helps someone. =P
