What is the cause of the “Failed to download bootstrapper files” error message in Synapse X

While some people encounter this error immediately after launching the program, others encounter it during use. There may be several reasons for this error.

Perhaps the application does not have the necessary administrative rights, or it has been blocked by your Internet service provider or network provider. Also, your antivirus program may have flagged the application, which may prevent it from being used correctly.

In this tutorial, we will list different methods to solve this problem. Once these problems are fixed, the “Synapse X – Failed to Download Bootstrapper Files” error should also be fixed. Without further ado, let’s get to the tutorial.

How to solve the “Failed to Download Bootstrapper Files” error in Synapse X

Allow Synapse X through your Windows Defender and Firewall

Antivirus and firewalls play an important role in protecting your system and data. An error can occur when your antivirus/firewall blocks files/services/processes that are important to Synapse X.

In this context, temporarily disabling the antivirus application and disabling the firewall may solve the problem. You can also add exceptions in the antivirus/firewall settings for files/services/processes related to Synapse X.

Note: Do this at your own risk, as disabling (or adding exceptions to) your anti-virus/firewall software can expose your system to threats such as viruses, Trojans, etc.

  1. Temporarily disable your antivirus program.
  2. Temporarily disable your firewall.
  3. Keep an eye on Windows Defender. If it acts as an antivirus/firewall program, disable it as well (at least disable Windows Defender’s real-time protection).

If you want to add an exception for Synapse X in your antivirus/firewall settings, add an exception for the entire Synapse X folder. For example, we’ll look at the process for Windows Defender.

  1. On the taskbar, click on the Windows search bar and type “Virus and Threat Protection.”
  2. Then click on “Virus and Threat Protection” in the list of results.
  3. Scroll to the bottom of the page and click on Manage Settings (under Virus and Threat Protection Settings).
  4. Then scroll down and click on Add or Remove Exclusions (under Exceptions).
  5. Now click on Add Exception, and then in the menu that appears, click on Folders.
  6. Now navigate to the Synapse X folder and click Select Folder.
  7. Then run Synapse X and check to see if the bug is fixed.

If the problems persist, download and install Synapse X again (with administrator privileges), with the antivirus/firewall program disabled (remember to add an exception for the entire Synapse X folder in the antivirus/firewall applications, including Windows Defender).

Run Synapse X with administrator rights

In the latest version of Windows, Microsoft has improved the security and privacy features of its operating system. One such feature is the use of UAC to restrict access to important system resources.

This error may occur if Synapse X is not authorized to access protected system resources. In this context, running Synapse X with administrator privileges may solve the problem.

  1. Right-click the Synapse X shortcut icon, and then select Run as administrator.
  2. Now check if Synapse X is working properly.

Use another network or try to use a VPN client

Internet service providers use different types of techniques and methods to control traffic and protect their users. You may encounter this error when an important file/service/resource is blocked by your ISP. In this context, using a VPN can solve the problem. You can use another network or access point from your cell phone.

  1. Download and install the VPN client of your choice.
  2. Now run it and connect it to the desired location.
  3. You can use another network or access point on your phone (but be careful about the size of the download).
  4. Then check for errors in Synapse X.
