Hello, I recently had to reinstall windows so that means I needed to update my computer. I'm trying to upgrade to service pack 3 but I always get this Copy Error. [[ "Setup cannot copy the file mdmrpci.inf. Ensure that the location specified below is correct, or change it and insert 'Windows XP Service Pack 3 Source Files' in the drive you specify." Copy Files from: (drop down) browse ]] I have no idea what do do. Thanks in advance.
