Opening a 32-bit database in the 64-bit version of MS Access

If you attempt to open a Microsoft Access database which is designed for the 32-bit version of the software, when you are using the 64-bit version of Acces, you may get a blank screen. If this happens, attempt this workaround.


  1. Holding down the SHIFT key, open the database so none of the forms present run automatically.

  2. Try clicking on a form and see if it prompts you to correct an error in Visual Basic like this one:


3. If you see these lines which begin with 'Declare Function', try editing them by adding 'PtrSafe' after 'Declare'. This will indicate that the database can be run in the 64-bit version of Access.
