It is important that your installation of Access is completely up to date with all service packs and hot fixes (there are lots!).
We recommend that you run Microsoft Update or Office Update regularly.
If you experience odd error messages during the operation of our database it is most likely that your installation of Access needs updating.
32bit or 64bit Demo ACCDE file? This refers to the version of Office that you have installed, not the version of Windows. If you know how to tell which you have then great otherwise, try 32bit and if that didn't work try 64bit :o)
The full version ACCDB file contains the source code for both so will work on either.
