You can create a registry key that will add the directory as a trusted location and will not show the warning anymore. What's nice about this method is that you can easily automate this to happen on the computers where you deploy your app. See method #2 or #3 in this blog: http://www.accessrepairnrecovery.com/blog/fix-microsoft-access-security-notice
And in case the blog ever gets removed, here is the important bits: [HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Access\Security\Trusted Locations\Location20] “Path”=”C:\Database\” “Description”=”My Database location”
Explanation about the key: – The number “14.0” is the version of MS Office. You can change the numbers that represent the version you are executing.
– The “Location20” is a unique name that you assign. 20 can be any number that is not previously used. Other programs include default MS Access wizards, already have used other numbers. But if you want to make more than one path as trusted location, then each location must end up with different number.
– The “C:\Database\” is the physical path that you want to set to be as Trusted Location. You can place any path that you choose here.
By copy and pasting the above coding into a text file and save it with a name such as RemoveSecurityWarning.reg, you can then run the file into your PC’s registry just by making double click on the file.
