Error 2739 on installing Adobe Creative Suite 3

Hello there,
I am having problem with the installation of the Adobe Creative Suite 3 on my Windows Vista OS. I was starting the usual installation process and upon running the Setup.exe file, this error message popped up on my screen:"This software cannot be installed because JScript is not properly registered.
Please repair JScript and then restart the installer." After this, my installer simple closed, and when I tried to check if it was still in Task Manager I found it together with an error message stating: "Setup has encountered an error and needs to close. Error Code: 2739."
This is really bugging me for a while now, so could you people help please.
Any kind of advice is welcome.
