# Troubleshooting

## Updater won't open

**Make sure that:**

1. Java is installed on your system.
2. Java version is atleast 8
   * to check which java you have, open terminal and write `java -version`&#x20;
3. Updater is grant on firewall
4. Updater has execute permissions

## **GUI won't open**

* **Check if your OS and CPU is supported, if you are unsure:** [**check the compatibility chart**](https://morpheuslauncher.it/#os-compatibility)&#x20;
* If on windows, make sure you have installed visual c++ runtime:\
  for x64: [https://aka.ms/vs/17/release/vc\_redist.x64.exe](https://aka.ms/vs/17/release/vc_redist.x64.exe)\
  for arm64: [https://aka.ms/vs/17/release/vc\_redist.arm64.exe](https://aka.ms/vs/17/release/vc_redist.arm64.exe)
* if on linux, check if `morpheus_launcher_gui` has execution permissions
* old windows defender definitions can false flag the gui, keep windows and windows defender updated, then check if `morpheus_launcher_gui.exe` got false flagged
