I'm kinda lost in the action of fixing my registration in order to install a new program. The infamous "Error 1606, could not access allusers...etc" was a problem, and I needed to fix the registration to solve the problem. In doing so, I followed an official Microsoft response http://support.microsoft.com/default...en-us%3B315352 although the registration key

Common Administrative Tools

wasn't in the library.

Would it be by any chance my computer, or a corrupted tutorial to fixing a unique problem?

-any help will be appreciated, i've considered creating a key? but, im not willing to take that chance
