Configure League of Legends path

cslol-manager will attempt to auto-detect your League of Legends installation.If auto-detection fails, you’ll be prompted to manually select your League installation directory. This should be the folder containing League of Legends.exe, typically:
C:\Riot Games\League of Legends\
You can change this path later in Settings if needed.

Troubleshooting

​

  1. Close cslol-manager

  3. Select “Run as administrator”
The application will create an admin_allowed.txt file to remember this setting.

​
Non-English Windows error

If you’re using a non-English version of Windows and experience issues, you may need to apply a registry fix. The zip bundle includes FIX-NON-ENGLISH.reg that can help resolve these issues.
Only run .reg files if you understand what they do. Always back up your registry before making changes.

​
Asian server check error

If you see an error message like “因封禁，亚洲服不支持!” (Asian servers not supported), this means cslol-manager detected you’re trying to use it with an unsupported server.
