Disable Advanced Security Xfinity

When you use advanced security Xfinity xFi, it provides a safer viewing experience. When adding a security level it can cause problems for the application. Therefore, if you use the advanced xFi security, it can block access to the Synapse application. With this in mind, you can disable this security measure as follows:

  • Start the application or the xFi site and click on “More”.
  • Now go to “My Services” and uncheck the “Advanced xFi Security” checkbox.
  • Then restart the Synapse X application and check if the “Failed to download startup files” error has been corrected.

Run Synapse X with administrator rights

In the latest version of Windows, Microsoft has improved security and data protection features of its operating system. One of these features is using user account control to restrict access to critical system resources. This error can occur if Synapse X does not have access rights to protected system resources. In this context, the problem can be solved by running Synapse X with administrator rights.

  • Right-click on the Synapse X shortcut icon and select Run as administrator.
  • Now check if Synapse X works correctly.

Use VPN

VPN or virtual private network creates a secure tunnel for transferring data packets. If your Internet service provider has blocked your connection to this tool, VPN can offer a practical solution. While the VPN hides your ISP and gives you access to websites with geographical restrictions, it can also be useful when you want to access Synapse X.

So download your favorite VPN, install it on your computer and select the region from which you want to access this software. Then run the Synapse X application and check if there is a “Download launch files failed” error.
