![]() If you distribute your applications with some sort of installer, such as Inno Setup, then you can set the trusted location as part of the setup process. The locations appear as subkeys under the following registry entry ("16.0" is the version number for Office 2016 , earlier versions will have a different number there): HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Access\Security\Trusted Locations Adding a Trusted Location via an Installer Trusted locations added through the Access user interface are stored in the user profile section of the Windows Registry (i.e., the HKCU hive). ![]() If the user has a full version of Access, then they can do this via File > Options > Trust Center > Trusted Locations >.

See the "Mark of the Web" section above for detailed instructions to "Unblock" the downloaded file. There are a few ways to work around this issue: Remove the Mark of the WebĪs described above, this approach requires modifying the downloaded file before opening it.

For the time being, users have the option to enable these macros at startup. Microsoft announced an upcoming change in how it handles code in Office applications–including Access applications–that are downloaded from the internet.īeginning with Version 2203, set to release in early April 2022, VBA code will be disabled automatically with no manual override option if the file was downloaded from the internet or another untrusted source. ![]()
