I can’t install Synapse X, how can I fix it?

If you’re experiencing any game-related issues, the best way to troubleshoot and resolve them is by installing the latest Roblox update. This patch resolves a number of issues and updates the game.

Here’s how to update Roblox:

  1. In order to update Roblox, you will need to first log in to your account and then go to the Roblox website.
  2. Once on the website, click on the “Updates” button in the top-left corner of the screen.

Roblox crashes when I use Synapse X, how can I fix it?

First, make sure that your computer is up-to-date and has the latest security patches installed. If you have other mods installed together with Synapse X, try and disable the other mods first to see if it helps. If not, try these steps:

  1. Right click on Roblox
  2. Click “Properties”
  3. Go to the Compatibility tab
  4. Enable “Run this program in compatibility mod for” and choose Windows 7 or 8.
  5. Enable “Run this program as an administrator”
  6. Click “Apply” and then “OK”

Roblox should work fine now.

Why does my antivirus warn me about the file?

The cause is simply because of a false-positive warning. This means that the antivirus software may incorrectly flag a file as being a potential virus, even when it is not. Almost all script executors injects into the game and edits files, which is similar to how actual viruses might act. This means that some antivriuses will give a (false) warning about the file, since it’s unsure.

You can bypass this by temporarily disabling your antivirus while using the mod menu.

Is Synapse X safe?

There are no known safety concerns associated with Synapse X, and the tool has been praised by users everywhere. It’s definitely a safe tool.

With that said, be sure to read the installation instructions carefully before downloading and installing. If you experience any problems while using Synapse X, check out our guide above.
