All welcome! Appeared suddenly following problem on the operating system Windows XP. Installed Microsoft Office 2003. If you attempt to open a file with the extension xlsx first crawls mistake about what this file is not found (and thus reveals his full directory in error, though of course the file is) then if you click on "OK" all the same Excel opens it, but he opens it with the notation "Read Only" and naturally does not overwrite the file if it made any changes. I thought flew component "Compatibility Pack 2007". I deleted it and put the "Compatibility Pack 2010" but the problem remains the same.
But the interesting thing is that if at first just open Excel and leaving it open to try to open a file through a conductor, it opens without window appears with an error and is not marked "Read Only" and of course no problem giving resave the file. The problem is seen only with the extension xlsx, xls with the extension of such problems is not observed.
