Win XP outlook 2003 archive.pst file copied and moved to a new PC with Windows 7 outlook 2010. Unable to open the .pst

The archive.pst was copied to a dvd from the old machine and pasted to a new foler on the new machine. The read only attributes have been unchecked. I have tried opening the file through outlook, used scanpst on the file and even used several versions of third party software. The result is always the same - 'archive.pst is not an outlook .pst file'. I am obviously paying the price for not researching the proper file transfer technique. The archive represents 6 years of emails and is ~1.1gig. The original .pst file is no longer available on the old machine. Any help will be gratefully received

In addition to Roady's excellent advice, while Outlook is closed make sure that the PST is not marked "read only." You can check this attribute by right-clicking on the file and scrolling to properties. Microsoft

what Kathleen said is very important. I found that is my problem. Nothing complicated. Just uncheck the "Read Only" Then it works.
