    Can't update reader - files in use by adobe 8.1


      I have tried to update to adobe reader x as I cannot view some things online.  My computer runs Vista.


      Error message comes up during installation:  Files in use by Adobe 8.1, close these then retry.   Adobe 8.1 has been deleted from the computer using uninstall and manual deletion.  Still same error message.


      Using the troubleshooting guide, I tried to delete Adobe 8.1 manually.  I tried to delete the files AcroIEHelper.dll, AcroPDF.dll and pdfshell.dll from my computer using command prompt, but computer says access denied.  When I try to remove them just by deleting them out of program files, computer says I do not have permission (although I am administrator).


      Any ideas???


      Thank You
