Synapse X Failed to Download UI Files: 5 Simple Fixes to Use

Roblox fans tend to modify certain game features using Synapse X, but the software sometimes fails to download the UI files as you try to launch/install the Synapse application.

While the error may appear due to various reasons, it is easy to fix, as we will show in the ensuing sections of this guide.

Why has Synapse X failed to download UI files?

Below are some of the causes of the Synapse X failed to download UI files issue:

• Antivirus interference: If Synapse X failed to download files or find Roblox, it might be because your antivirus software is blocking the app. The solution to this is to disable your antivirus temporarily and add an exclusion.
• Lack of privilege: Sometimes, this issue might occur because you don’t have administrative rights. You need to run the app as an admin to solve the problem.

What can I do if Synapse X has failed to download UI files?

Here’s what to do first:

• The Synapse X app may sometimes fail to work due to a problem with the network connectivity. In this case, you can try changing to a different network or use your mobile phone’s internet through the mobile hotspot.

1. Disable the real-time protection and add an exclusion

1. Click on the Windows Security icon in the system tray.
2. As the Windows Security app opens, click on Virus & threat protection on the right.
3. Next, go to Virus & threat protection settings and click on Manage settings.
4. On the next screen, go to Real-time protection and turn it off.
5. Now, scroll down, and under Exclusions, click on the Add or remove exclusion link.
6. On the Exclusions page, click on Add an exclusion and select Folder.
7. Now, look for Synapse X and select it to add an exclusion for it.

You can try launching Synapse X, and it should be working now.

But, if you are using a third-party security solution, turn it off temporarily or add Synapse X as a trusted item (add to the exclusion list).

2. Open Synapse X with administrator rights

1. Right-click on the Synapse X shortcut icon
2. Select Run as administrator.
   

Now that the Synapse X software has the right to access the protected system resources, the failed to verify UI data Synapse X error should be fixed.
