Temporary folder say access denied when I try to click to open. Any advice?

Are you logged in as administrator? Or another account that has administrative priviledges?

argh... caps !

Are you logged in as administrator?  Or another account that has administrative priviledges?

If you do have Administrator priviledges, then something may have removed you from the permissions for that folder.

Try going to the folder in question, right click and select properties. Click on the Security tab and see if your username is in the list, if not, then add it by clicking Add, then enter your username in the text box and click check names, this should see if the name is valid and probably add your computername to the username. click OK and then you should see your name in the Groups or User names list, just select full control and ok that should be it
