Did you make sure the DP is not already mounted before opening Casper Admin?
I did indeed. I've also setup debugging on the Casper Admin app courtesy of another discussion on this board and got the following from the debugging log:

@Chains what OS is installed on the computer you are attempting to open Casper Admin on? If it's macOS 10.12.x that may be your problem. I'm pretty sure you need a newer version of Casper Admin to be compatible with macOS 10.12. If you have a computer with Mac OS 10.11.6 or older give Casper Admin a shot on that to see if it works properly.
@mpermann and @Chains We had the same problem with 9.82 and 10.12.x. You'll probably need to get to at least 9.93 before you can use Casper Admin with Sierra. One thing I did as a work around is create a 10.11 VM and use that for any CasperAdmin needs until we upgraded a few weeks ago.
@tdclark It is indeed the fact that I am on 10.12, as running Casper Admin on an El Capitan Mac works perfectly. luckily is due to the fact I've only just started and its only a couple of the IT Macs that have been updated to Sierra we are going to re-image them with El Capitan. Once the organisation wants to go ahead with an upgrade to Sierra, if they do, then we'll go ahead with updating Casper, but hopefully I'll have a while before that happens to learn Casper in a bit more detail.
strange indeed!
I'm running 2 versions of Casper Admin successfully on a Sierra based mac.
I have had this issue before.
Although the Volume may not show on the desktop, it may still exist...
I basically ran diskutil unmount via terminal to be sure and found that this was successful.
G'Luck!
