Been through everything on-line and everyone has the same answers that do not work and people apparently do not read completely the  word for word problems that MANY others are having as well. 

Anyhow I can not get admin access to ANYTHING on my computer. EVERYTHING that is tried pops up a window that says "To continue, type an administrator password, and click yes" HOWEVER the "yes" button is greyed out and the ONLY option is no that aborts everything and nothing can be done. 

I got into some area that shows an admin account is present but I cannot access it. Going into User Accounts does nothing other than pop up the previous mentioned window. 

So who is an expert out there that has THE answer that works????????????
