Webroot Internet Security Plus for 2016 using the disk won't work?

Hello bearsun704,
 
Welcome to the Webroot Community,
 
You do not need the disc to install Webroot. Please follow below.
 
If you have a new keycode, you can activate it as follows:

1. Open SecureAnywhere.  
2. Click the gear icon next to My Account. Your account panel displays. [img]http://sw.nohold.net/Webroot/Images/myaccountdetails.png[/img]  
3. Under Activate a new keycode, enter the keycode you want to add and click Activate. Note: your keycode is a string of 20 alphanumeric characters. It is unique and holds the information about your subscription. You may choose to copy and paste your keycode when prompted, to ensure that the characters are entered correctly.

If you would like to also add your keycode to your online management account, click here for instructions.
 
Also you will need to Submit a Support Ticket to have them transfer your Passwords from old keycode to the new keycode. This is a free service with a Webroot subscrition.
 
 
Hope this helps?
