SYMPTOMS
You use the Microsoft Access Developer Extensions 2007 (ADE 2007) Package Solution wizard to package a Microsoft Office Access 2007 database application. When you install the packaged application on a computer, you receive the following security concern message when you open the packaged application:

A potential security concern has been identified.

Warning: It is not possible to determine that this content came from a trustworthy source.

You should leave this content disabled unless the content provides critical functionality and you trust its source.

File path: < >

This file might contain unsafe content that could harm your computer. Do you want to open this file or cancel the operation?



CAUSE
This issue occurs when you select an All User location in the Root Install folder list in the ADE 2007 Package Solution wizard. The application is not trusted for the current user.



RESOLUTION
To resolve this issue, select a Current User location as the root installation folder in the ADE 2007 Package Solution wizard. Then, make sure that each current user on the computer installs the database application.

Note For more information about how to perform this operation for a user who does not have administrative credentials, see the &quot;More information&quot; section.



STATUS
Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the &quot;Applies to&quot; section.



MORE INFORMATION
In the ADE 2007 Package Solution wizard, the following All User locations appear in the Root Install folder list:
 * System Drive (All Users)
 * Common AppData (All Users)

Note In Windows Vista, this location has Read-Only permission.
 * Program Files (All Users)

Note In Windows Vista, this location has Read-Only permission.

When the root installation folder for the application is set to a Current User location, the application is trusted for the current user on the computer. The following Current User locations appear in the Root Install folder list:
 * User AppData (Current User)
 * My Documents (Current User)
 * Desktop (Current User)

When the current user installs the database application, the database application is trusted by only that user account.

The current user must have administrative credentials to install the Access runtime. A current user who does not have administrator credentials can use one of the following methods to install the database application that requires the Access runtime.

Method 1

 * 1) If the Access 2007 runtime is not already installed on the computer, package the database application by selecting the option that requires the Access 2007 runtime to be downloaded.
 * 2) Ask the administrator to install the database application on the computer.

Note The Access 2007 runtime is downloaded and installed when the administrator installs the database application.
 * 1) Install the database application under the profile of the current user.

Method 2

 * 1) Ask the administrator to install the Access 2007 runtime on the computer. Then, give the current user a package that contains only the database program file or files.
 * 2) Install the database application under the profile of the current user.

Method 3

 * 1) Ask the administrator to install the package that contains the Access 2007 runtime.
 * 2) In the application package file folder, run the  .msi file.

If you open the database on a computer that has a retail version of Access 2007, you can trust the content in the database by clicking Options on the Security Warning Bar. You can also create a trusted location for the folder that contains the database. To do this, follow these steps:
 * 1) In Access 2007, click the Microsoft Office Button, and then click Access Options.
 * 2) Click Trust Center.
 * 3) Click Trust Center Settings.
 * 4) Click Trusted Locations.
 * 5) Click Add new location.
 * 6) In the Microsoft Office Trusted Location dialog box, click Browse.
 * 7) In the Browse dialog box, locate and select the folder that contains the Access database, and then click OK.
