Need latest version of ISScript.msi

I have had to re-install XP on an Inspiron 6000. AS I am reloading drivers I keep getting this error message: "The ISScript engine on this machine is older than the version required to run this setup. If available, please install ISScript.msi, or contact your support personnel for further support."

I am seeking assistance in finding where to download the lastest version of ISScript.msi, or other solutions to this problem.

Thanks in advance for your help!
