Solution: Modify Windows Registry

To fix this issue, you can set a registry key that forces Office to use the default browser for opening links.

Steps:

1. Close all programs.
2. Press Start → Run, type regedit, and click OK.
3. Navigate to the following key (create it if it doesn’t exist):

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\9.0\Common\Internet

1. Make sure the Internet subkey is selected.
2. Go to Edit → New → DWORD Value.
3. Name the value: ForceShellExecute
4. Double-click it and set the Value data to 1.
   "ForceShellExecute"=dword:00000001
5. Click OK and exit the Registry Editor.

Result:

This change forces Office to open hyperlinks using the default browser, allowing proper authentication and access to the Mavim Portal.
