where would I get my invitation code from

Hello rlewis4508,
 
Welcome to the Webroot Community,
 
 
Please uninstall WR from your iPhone. You have installed the Business version which does ask for an invitation code.
 
At this time, there is not an antivirus option available for Apple iOS devices. Because of how Apple manages the apps available in their App Store, there is not a need for one currently. This may change in the future but at this time is is extremly hard/almost impossible to infect an iPad/iPhone
 
Webroot does offer two apps you can download from the App Store to backup your files and protect your internet browsing, called SecureWeb and Backup & Sync. You can find either of them by searching for "Webroot" in the App Store on your Apple iOS device. For more information on both of these products please use the information below.

Webroot Backup & Sync (for SecureAnywhere Complete subscriptions only)

To make sure you're following these instructions for installing Webroot SecureAnywhere Internet Security Plus or Webroot Secure Anywhere Complete.
 
iOS Download Instructions
To download the SecureWeb app:

1. If you have not yet created a Webroot account, go to https://my.webrootanywhere.com. Click Sign up now to begin creating the account.  
2. Open the App Store on your device and search for “Webroot SecureWeb.” Tap to install the app. Alternately, you can download and install the SecureWeb app from iTunes at: http://itunes.apple.com/us/app/webroot-secureweb-browser/id460986853?mt=8  
3. Enter your Apple ID password. The SecureWeb app opens and installs on your device. Once installed, you will see the Webroot SecureWeb icon on your Home panel. Tap this icon to open the app.  
4. To access Password Management functions, tap the key icon in the SecureWeb toolbar. Enter your SecureAnywhere user name and password. This is the same login that you use to access your Webroot account at my.webrootanywhere.com. If you have not yet created a Webroot account, go to my.webrootanywhere.com. Click Sign up now and complete your registration. When SecureWeb validates your Webroot credentials, a green checkmark appears above the key icon.
5.  You can also see  Password Manager in Webroot SecureWeb.   Here's an KB article that you can look at for information! . Please have a look here  
6. For more information, see Webroot SecureWeb for iOS Help.

 If you're still encountering any issues, it's possible the issue could be related to the permissions granted to your account.  To check your account permissions, sign into http://my.webrootanywhere.com, click your email address at the top right of the console, click Manage Users, and click the little person with the pencil icon on the right side of the screen.  Ensure that all of the values for your user are set to either Access or Admin level and that there are checks in the Passwords and Passwords Services boxes.
 
Now if you are still having issues then you can submit a Support Ticket and they can look into this for you free of charge with an active subscription.
 
Hope this helps?
