I had this issue last week. We're running JSS 9.92 and the version of Recon was 9.91. Using Recon 9.92 resolved the issue. These were my errors -

I know with JSS 9.91 it would fail because of a version check it did with the binary. We are hosted so the version is technically 9.91.########## which fails a comparison with 9.91.

I have had this problem since at least January whenever I run Casper Remote. It always says that the latest binary isn't installed and once again downloads and installs it. I reported this and the Quickadd issue to Jamf. If @corbinmharris is right then they fixed the quickadd issue but since I am still on JSS 9.91 and don't know about the other issue. I am hoping they finally fix it, not a real problem but it is really annoying for our support staff to have to wait for the binary to install every time they need to run Casper Remote for to either install something or to access a remote computer.

Ah, in that case, it may be that my version of Recon is too new. I'm using Recon 9.92 and my JSS is on 9.81. I'll download the 9.81 version of the suite and give it a go.

Watch out if you have string based ea's set in the jss because 9.81 quickadd will wipe them.
