- Open the Start Menu Tab and go to Settings from there.

If the problem still persists, follow the next solution:
3. Turning off Your Antivirus Software:
Windows Defender or any other third-party antivirus software could also block the skse64 tool from launching.

If you use Windows Defender, then follow these steps:

- Click on Manage Settings and turn off Real-Time Protection. Save settings and start the game again.

For AVG antivirus users:
- Click on AVG Icon and find the Temporarily Disable AVG Protection option.
- Check it and set the time as per your preferences.

- Apply changes and see whether Skyrim could run smoothly with the skse64 modding tool or not.
4. Tweaking Antivirus Software for Some Exceptions:

If you use Windows Defender as your primary antivirus software, then follow these steps:
- Go to Start Menu and type “Windows Defender” in the search box.
- Open Windows Defender and from the left menu select, the “Virus and Threat Protection” option.
- In here, select “Manage Settings” and you’ll see a new tab named “Exclusions”.

- Save settings and run the game again for changes to get applied properly.
For McAfee users;
- Open the software and click on the Manage Security option.
- Click on Virus and Spyware Protection. In there, you have to select the Schedule and Run Scans option accordingly.
- From there, simply select Schedule Scans. A new window will pop up in which you have to find the Add button option under the Excluded Folders option.
- Add Skyrim from the game directory and click on save for the changes to happen.
- Run Skyrim on your PC to see whether the skse64 crash on starting issue has been resolved or not.
5. Keep SKSE64 Updated:
Mind you that the tool won’t launch if you are trying to pair it up with an old version of Skyrim.
Similarly, the old skse64 won’t work with an updated version of the game.
For both the tool and game to work properly, you’ll have to keep them updated to their latest versions.
In case the game has got updated but the tool has no recent update, then you can simply roll back the game to its previous version.
For rolling the game back to its old version, follow these steps:
- Open the web browser you are currently using and navigate to the Steam Database site accordingly.
- Next, type Skyrim in the search box and hit enter button.
- In here, you have to look out for the “The Elder Scrolls V: Skyrim” entry.
- Simply write down the APPID number of the game in the search box.
- Click on the number and a new popup window will open. In here, select the Depot option.
- Next to “Skyrim Special Edition.exe”, you have to write the Section ID number of the updated game.
- After clicking on the serial number, a new window will pop up. Select, Manifests option in that window for further process.
- In the search box, write down the number, which is older than the newest release update. For instance, if an update came 3 days ago, you have to write an older number than 3.
- After you get done with this, go to your Desktop menu and right-click on the Steam Launcher shortcut.
- Click on the Properties and type console in the Target box.
- Don’t leave any space while typing Console. Save the settings and run Steam launcher from that shortcut again.
- Click console and type ‘download-depot’ along with the APP ID number or manifest number that we already got from the browser and press enter.
- From there, navigate to the folder where the older version is downloaded through the Console option.
- Find the exact download and copy it.
- Simply paste it in the game installation folder using Control+C and Control+V commands.
- Now you have again reinstalled the older Skyrim version that will now work with the skse64 modded tool.
- It will probably solve the crashing or not working issue.
However, if you are still unfortunate, then we have one last solution for you:

In that aspect, follow these steps:
