I recommend creating your own .reg file and saving the trusted location with a unique name specific to the location or app being trusted. For example:
"Description"="Your Description goes here ...."
TIP: If you export an existing trusted location as a .reg file its easy to use it as a template
Using this approach gives you more control over the registry entry.
It also allows you to add entries in one reg file for:
a) several locations at once
b) multiple Access versions if needed e.g. 12.0, 14.0,15.0,16.0.
NOTE: It doesn't matter if the user hasn't got all those versions or locations as anything irrelevant will be ignored.
In fact before A2019 was released I wrongly assumed it would be v17.0 and added trusted locations for that in advance. In the end none of those were required (as its still 16.0) but the extra entries aren't a problem
The attached reg file contains 2 sample entries for different locations for the 4 versions of Access listed above. Unzip, right click and select Edit from the context menu to view it in Notepad. Or right click and select Merge to add to registry.
Hope that helps
