VC++ 6.0 App must run as Admin to access a DB in the Common Application Data area

I have an old C++/MFC app written with VS 6. I am trying to make it compliant with Windows Vista and 7 by moving the DB directory to the Common Application Data area. But when I try to open the Access DB using DAO it reads the primary table, finds no records, and reports that no data is found. However, if I select "Run as Admin", then records are found and the app runs like normal and without any issue.

Should I be storing the database in another location? If not, why does it fail to read the table correctly?

Also, I have tried using the attached manifest, that I found online and modified slightly, but it does not seem to force the application to run as admin and so I still get the no data found message. I don't know much about manifests yet, so it could be that I didn't configure it correctly.

I would appreciate it if you could provide me with the correct location to store the DB, so multiple users on a single computer can access it and/or a method of getting this app to run as Admin.

Thanks for any help or advise you can give.

Can you try with:
<requestedExecutionLevel level="requireAdministrator" uiAccess="false"/>

Another way is to set ACL on AppData folder during the installation/before starting the application.

Regarding cacls command:

The initial comment to try: <requestedExecutionLevel level="requireAdministrator" uiAccess="false"/>
did not make any difference.

I did notice that if I copy the application to some other folder that is not under the Program Files folder, say C:\MyApp; then it seems to recognize the manifest and ask the user about allowing this app to control the system.  If I select Yes, then everything seemed to work fine.  Why is that?  Also, how do I avoid that popup everytime I start the application?

With regard to the second comment to use CACLS, the instructions seem to imply that you must specify a user name and I need it to support any user and not just the one that installs it.

What about this?
<requestedExecutionLevel level="asInvoker" uiAccess="false"/>

You can specify the user everyone.  eg

cacls xxx.mdb /E /G everyone:C

It keeps the old permissions /E
It grants (/G) everyone change permission (C)

I could not seem to find a suitable answer, so I just upgraded the application from VS 6 to VS 2008 and used a built-in manifest that seems to work.

No matter what I did, the VC++ 6 compiled app would not run from the Program Files folder.
