simple .vbs app executes normally on my win7pro workstation -- same .vbs app not executing on my win7pro laptop -- why?

I created a very simple .vbs app --- WScript.Echo "Hello World"   on my windows 7 profession workstation.  I double click the app (from Windows Explorer) and a messagebox appears on the screen that says "Hello World".   I created the same exact .vbs app on my windows 7 professional laptop, but when I double click the app (on the Windows Explorer on my laptop) -- instead of executing the app -- windows just opens up Notepad and displays the script --- WSScript.Echo"Hello World". 

I named the app test1.vbs.  It executes normally on the workstation but does not execute on the laptop.  I tried executing test1.vbs from the cmd line on the laptop -- and that also did not execute -- it only opened up Notepad and displayed the script. 

Is there something missing or something wrong with the installation of windows 7 professional on my laptop?  What can I do -- what should I do to fix this problem on my laptop?

Thanks
