Adding Trusted Location to Access Run Time

It is much easier to just copy your Access file to a folder that is already trusted by any user.

One example is %LocalAppData% which works even in a Citrix environment.

Create a folder here named you or your company and a subfolder named your application. Copy you database file to this, and provide a shortcut for the users.

Below are some instructions i found awhile ago which i had saved, which allow you to add trusted locations, allow network locations & include sub folders.

1. Use the search in Windows 7 or Windows 8 and type in "regedit.exe";
2. Allow Microsoft Windows Registry Editor to make changes to your system;
3. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Access\Security\Trusted Locations;
4. Add a DWORD by right clicking the Trusted Locations directory, selecting New > DWORD (32-bit) Value [or 64 bit QWORD as required];
5. Change the name of the DWORD to "AllowNetworkLocations";
6. Right click and modify the DWORD using "1" as the value;
7. Now add a new KEY to the Trusted Locations directory by right clicking the directory and selecting New > Key (You can rename this to something meaningful);
8. Right click the new Key and select New > Expandable String Value (for runtime 2013, just String Value for earlier version);
9. Change the name of this file to "Path" and then right-click and modify... the Value Data to the path or network name required (ie "Z:\" or "\servername" );
10. To include sub directories as trusted locations, add a DWORD by right clicking the new key, selecting New > DWORD (32-bit) Value [or 64 bit QWORD as required];
11. Change the name of this DWORD to "AllowSubfolders" and right click and modify... the DWORD using "1" as the value;

[HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Access\Security\Trusted Locations\Location(n)]

Access 2010:

[HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Access\Security\Trusted Locations]

[HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Access\Security\Trusted Locations\Location(n)]

Access 2013:

[HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Access\Security\Trusted Locations]

"Path"="C:\PathToDB\"
"AllowSubfolders"=dword:00000001
"Description"="The description"
"Date"="01.01.2007 12:00"
