Recently, on a Windows 7 Enterprise system, I installed Microsoft Office 2010. Trying to activate the product, using either Office Volume Activation Script for Z.W.T Keygen or EZ-Activator, the system responded with the following message: “Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.” Repeating the same job on a Windows 7 Professional System, everything went OK. Are there any ideas about what can I do? Any help would be welcome.
