Access Denied when installing drivers

[Arris]

Is it possible that the user named ‘Administrator’ is removed from the ‘Administrators’ group? You can check this by entering lusrmgr.msc in Start -> Run, and see in the Groups section if the Administrators group contains the Administrator user.

Besides that you can try if setting the User Account Control (Start -> Control Panel -> User Accounts -> Change User Account Control Settings) option is set to Never Notify to avoid UAC blocking the installation of the drivers.

Finally, if these options doesn’t work out, try to find out using Sysinternals Process Monitor what is bothering the installation of the drivers.

Hope this helps you and good luck with this weird problem! 😉
