Dear ARei_015,
Welcome to the Microsoft Community
Thank you for reaching out with your issue regarding the error message "This user does not have the required permissions to run Setup. Please run Setup elevated or with another user who has the required permissions" when attempting to run setup.exe from a Windows 11 ISO. I understand how inconvenient this can be, especially when administrative permissions should typically resolve such issues.
Let’s go through some steps that might help solve this problem.
- Verify User Account Control (UAC) Settings:
- Ensure that UAC settings are configured correctly.
- Open the Control Panel, go to User Accounts > Change User Account Control settings, and set it to the highest level. Disclaimer: Follow these steps to temporarily disable User Account Control (UAC). However, keep in mind that if you do so, your device may be vulnerable to threats. So please turn on it immediately once issue fixed.
- Disable Antivirus/Firewall Temporarily: Sometimes, security software can interfere with setup processes. Temporarily disable your antivirus and firewall, then try running the setup again. Disclaimer: Temporarily turn off antivirus protection. However, keep in mind that if you do so, your device may be vulnerable to threats. So please turn it on immediately once issue fixed.
- Check Group Policy Settings:
- Ensure there are no Group Policy settings restricting software installation.
- Press
Win + R, type gpedit.msc, and navigate to Computer Configuration > Administrative Templates > Windows Components > Windows Installer.
- Ensure policies like "Prohibit non-administrators from applying vendor-signed updates" are not enabled.
- Use an Alternative Method to Mount the ISO:
- Instead of running
setup.exe directly from the ISO, try extracting the contents of the ISO to a local directory or using a third-party tool to mount the ISO.
- Right-click the ISO file, select Mount, then try running
setup.exe from the mounted drive.
- Use the Media Creation Tool: Instead of using the ISO directly, use the Windows Media Creation Tool to create installation media on a USB drive. This tool ensures the latest version and proper creation of the installation media.
If these steps do not resolve the issue, please provide additional details about your environment, such as any recent changes made to the system or any specific error codes you encounter. We can then look into more advanced troubleshooting steps.
Thank you for your patience and cooperation.
