🛠️ Fix: GlobalProtect Script Error "Access Is Denied" on Vendor-Controlled Laptops

If you're trying to install or log in to GlobalProtect VPN and run into a script error that says:

“An error has occurred in the script on this page. Access is denied.”

— you’re not alone. This common issue can completely block access to GlobalProtect, especially on vendor-managed laptops or corporate devices with strict group policies.

The cause? Internet Explorer.

🔍 Why This Happens

Many older versions of GlobalProtect still try to launch Internet Explorer (IE) for authentication during installation or first-time login. On corporate-managed devices, IE is often disabled or locked down due to security risks — which causes GlobalProtect to fail when it tries to load the login page, resulting in the “Access is denied” script error.

This is a known problem that affects many users, particularly in enterprise environments where IT policies block the use of legacy browsers.

✅ The Simple Fix That Works

Here’s a proven workaround: install GlobalProtect using a command that forces it to use your default browser (like Chrome or Edge) instead of Internet Explorer.

Use this command:

msiexec.exe /i GlobalProtect.msi DEFAULTBROWSER=YES

By adding DEFAULTBROWSER=YES, you tell GlobalProtect to skip IE entirely and open the login process in whatever modern browser you’ve set as default — solving the script error instantly.

📘 Step-by-Step Instructions

1. Download the latest version of GlobalProtect.msi from your organization’s portal.

2. Open Command Prompt as Administrator.

3. Paste and run:

   msiexec.exe /i GlobalProtect.msi DEFAULTBROWSER=YES

4. Let the installation complete.

5. Launch GlobalProtect — the login should now open in your default browser, with no script errors.
   

This method works reliably on vendor-issued laptops where group policies block outdated browsers like IE. It ensures GlobalProtect integrates with modern browser security and compatibility.

🔎 Still Not Working?

If you're still having issues, make sure:

• You're running the command with admin rights

• Your system default browser is set to Edge, Chrome, or Firefox

• Your .msi installer is up to date

🧠 Final Thoughts

This solution is a lifesaver for users stuck with GlobalProtect login problems, especially in tightly managed enterprise environments. By using DEFAULTBROWSER=YES, you avoid compatibility issues with Internet Explorer and unlock a smoother, faster login experience.

No more script errors. No more dead ends. Just a simple fix that works.
