How to convert Access 32 Bit Database to Access 64 Bit Database

First, let me make clear what I'm saying.  Usually an ACCDE is created to protect the design of forms, reports, and VBA codein a database application.  The ACCDE may or may not contain the actual data tables -- often, it contains only links to the tables in another database (generally referred to as the "back-end", whereas the ACCDE is the "front-end").

If she has only 64-bit Access and the ACCDE was built with 32-bit Access, then she won't be able to open and run the ACCDE as an *application* -- she won't be able to run the forms and reports, and won't be able to execute any code it contains. 

All I'm talking about is a way to get to the tables (if any) and queries in the ACCDE.

To do that, she would open her copy of Access without selecting an existing database.  She would then tell it to create a new, blank database (not a web database).  She'd have to provide a name and folder path for that database, and then click the "Create" button.  Access will create the database and open it, and will probably open an intial sample table, "Table1".  She should just close that table.

She should then go to the "External Data" tab on the ribbon, and from the "Import & Link" tab group she should click "Access".  She'll tehn be shown a dialog prompting her to specify the source of the data.  She should enter or browse to & select the ACCDE that she's interested in.  She should also choose the option, "Link to the data source by creating a linked table".  The she should click the OK button.

She'll then be shown a Link Tables dialog where she can select the tables to be linked.  It will only show the tables that actually reside in the database she's linking to -- if the ACCDE has linked tables to a back-end somewhere, those tables won't appear.  She should then select the tables she wants to link, click the OK button, and Access will take it from there.

If it turns out that the ACCDE has only linked its tables, then she can import the table links instead of linking tables. She'd follow basically the the same process but instead of choosing the "Link ..." option, she'll choose "Import ..." instead. That will copy the table *links* from the ACCDE into her working database.

If the ACCDE contains stored queries that she wants to use, she can import them. To do that, she would use a similar procedure, except that she woluld choose the "Import" option, go to the Queries tab of the Import dialog, and select the queries she wants.
