SKSE64 is a tool that allows Skyrim mods to add functionality and scripting capabilities to the game. However, some users have reported that SKSE64 is not working properly and causes the game to crash or not run at all.
This could be due to various reasons, such as:
- Permissions: Steam and its apps may be installed in the Program Files folder, which contains critical Windows files. As a precautionary measure, this setup may prevent SKSE64 from running.
- Windows Firewall: Upon launching Skyrim, Windows Firewall might block certain processes, including the SKSE64 script extender.
- Antivirus: If you are running any third-party security software, it could potentially identify Skyrim and its game files as a threat and prevent them from launching correctly.
- Improper installation of SKSE64: There is a possibility that you might have skipped an important step during the installation of SKSE64 or downloaded an incompatible version for your current game version.
- SKSE64 is not compatible with the current game version: To ensure compatibility, SKSE64 offers different versions for installation. It is important to choose the version that is best suited for your specific Skyrim SE version.

Solution 3: Reinstall SKSE to Skyrim
- Go to the official SKSE website and download the latest version of SKSE that matches your version of Skyrim SE.
