It say's Microsoft Excel can't access the file, and that it could be for various reasons:

. The file or path don't exist (they do).
. Another program is using the file. (?)
. The workbook you are trying to open has the same name that other opened workbook (no).

Another thing is that MsAccess does not work, when I try to open a new project it immediately say's that it need VBA so it starts a long installation process which finishes asking to restart pc. After restart it has no effect I open access again and it starts the same process.
