Hi every body.

Can anybody help me to install Norton 2010 on my secon laptop. I have successfully installet it on my fisrt laptop,but when I put the disc into the drive nothing happens.The instructions say,click on "My computer" and in the list of files double click  Start exe.   Try as I may , i cant find this file anywhere!!!!

Ive tried clicking "run" then "browse" then looking for the files in C drive etc .

My laptop is a Packard Bell easynote , about 4 years old.

Please help an old Dummy.
