JustMock 2026 Q4 "Removed the legacy JustJockRunner.exe"

I'm currently running into the issue that I'm not able to execte UnitTest locally on a GridNode Server using JustMock.
https://www.telerik.com/support/whats-new/justmock/release-history/justmock-2026-q4-(2026-4-1110-621)
The Trace Output mentions that "The profiler must be enabled to mock, arrange or execute the specified target."
I'm able to get the test running again enabling the JustMock Profiler through the JustMock extension menu. But this isn't working with the GridNode Server.

How to deal with that?

Hi, thanks for sharing this issue.

We were integrated with the JustMockRunner.exe that has just been removed. I've implemented a speculative fix to tie us into the replacement EXE which seems to have a slightly different parameter line. Unfortunately I can't verify it because I don't have a dev environment set up with JustMock to be able to do so (the download for it is gated). Would you be interested in giving it a try?

For a speculative fix it works quite well!

Am I able to connect to the Grid Node 5.25 Server with 5.24 Clients - for those who won't upgrade to this temp. version?

Yes, the version above should have a compatible protocol with the v5.24 build on the download page. Naturally without the update on the client the fix won't be present unless they use a grid node.
