How do I get the Object Tree and Process guide to show up when I open a *.elt file?
Probably the elt file you opened is a part file.
it contains the model (either b-rep or mesh) that you wish to prepare for printing.
The Object Tree and Process Guide show up when you enter or create a 3DP Project.
Open up a new 3DP Project and load the the part (Add 3DP Component).
