I have Office Professional 2007 and have been using it fine. Lately when I open Access and try to open a file I have saved I get the message that DAO360.dll is missing. It is in my Common files>Microsoft shared>DAO. so I don't understand why it says it is missing.

I tried to repair with the CD but that didn't help.

Any suggestions?

    DAO360.dll is not necessary for Access 2007. Its included int he object library. It sounds like you may be running an app built in an earlier version which did need the reference. Try removing it from the selected references.

    Try re-registering DAO:

    1. Press Windows key+R to open the Run dialog.
    2. Enter or copy/paste the following line into the box:

    regsvr32 "c:\program files\common files\microsoft shared\dao\dao360.dll"

    If you have 32-bit Office on 64-bit Windows, use

    regsvr32 "c:\program files (x86)\common files\microsoft shared\dao\dao360.dll"

    1. Press Enter or click OK.

    Scott, .accdb databases don't use DAO360.dll, but .mdb databases still need a reference to this library in Access 2007 and later versions (if they use DAO of course)
