update error 800700c1

[Guest rph08]

i read through all the previous posts and tried all of the suggestions. my

only problem is that my computer will not allow me to change to run as an

administrator. the check box and wording is gray to where choosing it is not

an option. i also cannot pull up internet options. i get a box saying

"C:\Windows\system32\ADVPACK.dll is either not designed to run on windows or

it contains an error.", thus i cannot delete my temp internet files and my

defrag won't work. i'm thinking my computer has some serious windows issues

at this time. if anyone can help me figure out how to fix at least one

problem, i would be grateful! thanks!
