[4T5]

Hi Dudes,
My mate sent me a LEGIT copy of COD2 as he got it free with a GFX card he got for a Build, Anyways.
I cannot instal it and get the following error;
1607: Unable to Install Installshield Scripting Runtime.

I have odviously Googled and Searched my Bits off tried the suggested fixes and am now at a loss.
I could do with any easily explained fix or i am not going to be able to try this.
Thanks in advance and Kudos to whoever comes up with the Fix.
