# Powershell script (.ps1) are not runnable > Author: Junner > Date: 2/26/2025 When try to run PS script (.ps1), terminal came out an error: ```bash! .\*ps1 : File D:\Junner\setup_env.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170. At line:1 char:1 + .\*ps1 + ~~~~~~ + CategoryInfo : SecurityError: (:) [], PSSecurityException + FullyQualifiedErrorId : UnauthorizedAccess ``` Go open a PowerShell with administrator permission. `win`+`R` > type `powershell` > hold `ctrl`+`shift` then `enter` Open the permission for running PS script: ``` Set-ExecutionPolicy RemoteSigned -Force ``` And you can run your script. After excuting, remember to turn this permission off. ``` Set-ExecutionPolicy Restricted -Force ``` Another way to open permission for certain file is: ```bash powershell -ExecutionPolicy Bypass -File .\setup_env.ps1 ``` And this is just for temporary when using this prompt. After turning off the prompt, permission no longer exists.
