the installation is forbidden by system policy
This error indicates that a system policy is preventing you from installing the application. Here's how to troubleshoot it:
Troubleshooting Steps
- Run as Administrator: Right-click the installer file and select "Run as administrator". This grants elevated privileges that may bypass the policy.
- Check Group Policy Settings (for domain-joined computers):
- Contact your IT administrator. They control the Group Policy settings.
- If you are the administrator, use the Group Policy Editor () to review software restriction policies or application control policies. Look for rules that might be blocking the installer.
- Check Local Security Policy (for standalone computers):
- Open Local Security Policy ().
- Navigate to "Software Restriction Policies". If present, review and modify the rules.
- Disable User Account Control (UAC) temporarily (Not Recommended):
- Search for "UAC" in the Start Menu and open "Change User Account Control settings".
- Lower the slider to "Never notify".
- Reboot your computer.
- Attempt the installation.
- Important: Re-enable UAC after the installation for security reasons.
- Antivirus/Security Software: Temporarily disable your antivirus or security software. Sometimes these programs can mistakenly block legitimate installers. Remember to re-enable it afterward.
- Installer File Corruption: Re-download the installer file. A corrupted file can trigger policy restrictions.
- Check Event Viewer: Look in the Event Viewer (search for "Event Viewer" in the Start Menu) for specific error messages related to the installation failure. This can provide more detailed information about the policy blocking the installation.
Caution: Modifying security policies can impact system security. Ensure you understand the implications of any changes you make.
