Error during installation

[Nutsci]

Hey All,
Any help would be appreciated. I have installed Virtual Box (5.1.16r113841) but am getting the following error when trying to install the extension pack:

The installer failed with exit code 1: VBoxExtPackHelperApp.exe: error: Membership in the Administrators group is required to perform this action.

Result Code:
E_FAIL (0x80004005)
Component:
ExtPackManagerWrap
Interface:
IExtPackManager {edba9d10-45d8-b440-1712-46ac0c9bc4c5}

Thanks,
Nutsci

• Right-click on the VirtualBox, select Run-as-Administrator. Don't worry if you don't see your VM(s).
• Go to the Preferences » ExtPack » install the matching ExtPack that you downloaded.
• Quit VirtualBox.
• Launch VirtualBox again, either from the desktop shortcut or from the Start menu.
