### Script Won't Run
If your PowerShell session is running in **Constrained Language Mode**, some scripts and commands may fail to execute. To check the current language mode, run:
```powershell
$ExecutionContext.SessionState.LanguageMode
```
If it returns `ConstrainedLanguage`, you may need to switch to `FullLanguage` mode or run the script in a session with administrative privileges. Be aware that some security policies may enforce Constrained Language Mode, especially in corporate or managed environments.
If you run WinUtil and get the error:
**If the download fails**:
`"WinUtil is unable to run on your system, powershell execution is restricted by security policies,"`
1. Try the direct GitHub link:
```powershell
irm https://github.com/ChrisTitusTech/Winutil/releases/latest/download/Winutil.ps1 | iex
```
2. Force TLS 1.2:
```powershell
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
irm "https://christitus.com/win" | iex
```
> [!NOTE]
> On Windows 11, you usually do not need the TLS 1.2 command. Use it only if you encounter download or security protocol errors.
### Execution Policy Error
If you see an execution policy error when running the downloaded script, you can allow the current session to run unsigned scripts with this command:
```powershell
Set-ExecutionPolicy Unrestricted -Scope Process -Force
irm "https://christitus.com/win" | iex
```
This only changes the policy for the current PowerShell process and is safe for one-off runs.
### Interface Doesn't Appear
If Winutil downloads, but the GUI does not open or appear, try these steps:
1. Check if your antivirus or Windows Defender is blocking the script — add an exclusion if necessary.
2. Ensure you launched PowerShell / Terminal as **Administrator**.
3. Close and reopen PowerShell, then run the launch command again.
4. If the script still doesn't show, try running the script in a visible PowerShell window (avoid background/silent shells) to observe output and errors.
this means that your PowerShell session is in **Constrained Language Mode**, which prevents WinUtil from running.
