Windows 10: App will not connect to an Access database in new computer Windows 10 64 bit

When my old Windows 7 machine finally crashed I bought a new system with Windows 10 64 bit. My custom application will no longer connect to the access database. The database opens fine with Access but errors with 'Unable to open connection to database. Either file is missing or altered' when trying from my app. This application has worked flawlessly for the last 15 years with everything from Windows xp through Vista and Windows 7. Any suggestions? I am unable to open the source code and change anything due to the age of the application. Only thing I can think of that may be the issue is this is a 64 bit machine and all the computers I had before this were up to a 32 bit machine. Thank you for any help you can give.

Recover access database

Did you try this yet? http://support.microsoft.com/kb/283849

Run the Compact and Repair utility. To do so, follow these steps:

• If the database is open, close it.
• On the Tools menu, point to Database Utilities, and then click Compact and Repair Database.
• In the Database to Compact From dialog box, select the file that you want to compact, and then click Compact.
• In the Compact Database Into dialog box, enter a new file name, and then click Save.
  
  If the compact and repair does not succeed, you will receive a message stating so. This means the damage is so severe that it cannot be corrected.

Looks like you will need to rebuild the whole thing but at least you have the data still, right?
EDIT: Wait did you try this?

Convert a database to the Access 2007 file format

http://office.microsoft.com/en-us/a...-the-access-2007-file-format-HA010048406.aspx


You cannot convert a replicated database to the Office Access 2007 file format. However, you can use Access 2007 to create a replica of a database that is formatted in either the Access 2000 or the Access 2002 - 2003 file format.


More copy and paste:
[paste:font size="5"]Convert an Access 97 database, Convert an Access 95 database, or Convert an Access 2.0 database.

• Click the Microsoft Office Button
  
  , point to Save As, and then, under Save the database in another format, click the file format to which you want to convert.

• If any database objects are open when you use the Save Database As command, Access prompts you to close them prior to creating the copy. Click Yes to make Access close the objects, or click No to cancel the entire process. If needed, Access will also prompt you to save any changes.

• In the Save As dialog box, type a file name in the File name box, and then click Save.

Access creates the copy of the database, and then opens the copy. Access automatically closes the original database.

Windows 10 Upgrade 32-bit to 64-bit

So, Windows 10 Upgrade is being rolled out worldwide, and I have 'reserved' my upgrade.

Currently my computer is running Windows 7 Pro 32-bit. I'm planning to 'upgrade' it to Windows 10 64-bit (via fresh install, of course).

After reading many references, these will be the steps I'll do:

1. Let the "Get Windows 10" app upgrade my OS to Windows 10 32-bit
   
2. Note the activation key
   
3. Download the Installation Media for Windows 10, but choosing 64-bit instead
   
4. Perform a clean install
   
5. Reactivate using the activation key in Step #2
   

(Of course I'll backup my data first.)

However, I still have some questions:

1. On Windows 7, the activation key does not differ between 32- or 64-bit versions. Is it still so with Windows 10?
   
2. Will I be able to download a different architecture on Step #3?
   
3. Is there anything I need to prepare beforehand?
   

Thank you for your assistance.
