We currently have batch files to change the license level:
set ESRI_SOFTWARE_CLASS=Viewer
set path=%path%;C:\Program Files (x86)\ArcGIS\Desktop10.6\bin
ArcMap.exe
But what I need to is to check in and out a license without administrator rights, can I do that? I see in this post here, that other options I can do but nothing about checking in/out a license at all. I have not found much else to point me in the right direction.
