Windows 10 on domain.
I configured a PACS Archive location for query retrieve as administrator and it works.
If I log in as another regular user, it "You need to configure PACS locations."
How do I save these settings across users?

This was resolved by RadiAnt support via email.

I discovered C:\Users\[my admin profile] \AppData\Roaming\RadiantViewer\pacs.xml which has the settings. But this is only available to the admin user by default.

You can make pacs.xml available for all users of the Win10 computer by placing this file in the C:\ProgramData\RadiAntViewer\ folder.

However, only if no c:\users\USERNAME\AppData\Roaming\RadiAntViewer\pacs.xml file exists, the pacs.xml file from ProgramData will be read.
If the user already exists, a bad c:\users\USERNAME\AppData\Roaming\RadiAntViewer\ folder may have been created and if a pacs.xml is located in user's roaming folder, it will be prioritized.
So in that case, you need to delete the user profile, or at least the c:\users\USERNAME\AppData\Roaming\RadiAntViewer\pacs.xml file, and it should be ok.

Hey. I just wanted to give you a shoutout for posting this information. It is incredibly helpful and I couldn't find this information in the documentation!

Yes, we probably should add this to the manual :-)

Thanks! Very helpful!

For Domain Infrastructure It will better: it will Easy to administrate and maintenace the your IT infrastructure.

1. Grab the pacs.xml file
2. Will make "Radiant" Group in AD
3. in Group policy Add the Deployment for this "RADiant" group, to Deploy just this pacs.xml file to the %userprofile%\AppData\Roaming\RadiAntViewer\ for the all Domain group users.
