I bought Symantec Internet Security 2004, and each year after I have bought the renewal online.

I want to format my computer and reinstall it, but I can't find the installation files and the updated files.

Also, I'm wondering if I just backup the folders onto disc and then move them back into the c drive, will that be the same as being installed?

The Symantec web chat support is terrible.  Very slow typing and couldn't answer this question.  Also said he was only trained for the 2005,2006 editions.  

(by the WAY, this is a Japanese version of the program, but the file names are in English and I assume everything is pretty much the same as English versions)
Unfortunately, I would suggest you contact Symantec directly about GETTING a current copy of the program SINCE you have paid for it and are a regular customer.  buy the newest version of it. its cheap and my scan times were cut by 35-40% with the new one. i was in the same position as you are and its so much easier, and saves a *censored* LOAD of timeIf I was you (I've been renewing my symantec online for 5 years) I would copy all your files to CD and then re-install them where ever and attempt to go online and renew your subscription. You wanna find the files, pain in the arse but your gunna have to kick your little 'search files' buddy into gear. They shouldn't be too far spread (the FILS I mean), as long as you get the main application, you don't need all your 'update' files cos when you re-apply it should update automatically. Is this too easy or am I missing the point?...Thanks for the replies.
I kept renewing my 2004 version simply because it is cheaper that way and it works.
I renewed it only a few months ago (for a year) so I'd really rather avoid formatting the computer and then losing my 9 months of remaining subscription and paying again.
  
Actually, I found the original installation file, but I can't find the update file that I downloaded after paying for it.  Since it doesn't seem as easy as I thought, I guess I'll have to contact Symantec Japan, which I would have rather avoided.  
My brother had the same problem. Called Symantec and problem solved in 10 minutes.
