The most common causes of connection errors are:

  1. No Internet access
  2. A firewall, company network, or antivirus software has blocked access to the File Viewer Plus online activation server located at https://sharpened.com.

What steps can I take to fix connection errors?

  1. Verify that you have an Internet connection.

    If you are not connected to the Internet, please enable Internet access and restart File Viewer Plus.

  2. Check if something is blocking access to the activation server.
    • If you are on a corporate network, please check with your system administrator to see if your network allows access to https://sharpened.com. If not, your network will need to allow access before using File Viewer Plus.
    • If you have antivirus software enabled, check to see if it blocks access to File Viewer Plus. For example, Norton Internet Security has a "Smart Firewall" that may block access and can be configured to allow specific programs to have access to public networks. You may also temporarily disable antivirus software protection, start File Viewer Plus, then re-enable protection immediately afterwards.
    • If you are using Windows Firewall, which is turned on by default in many Windows systems, follow the instructions below to add File Viewer Plus to the Windows Firewall exceptions list.
