Yeah, that registry entry is the “DEADLINE_PATH” variable. Often, DLC will die in these installers and they can’t report the issue.
Charles’ request to run it from the command line should help narrow down if that machine is having connectivity problems, but if @mirkoj did install it to “Deadline” instead of “Deadline10” he’ll need to adjust it for his install.
Also, checking the bitrock installer logs will help here as it will outline the issue. What I’ve also seen is that the certificate for DB communication may be on a mapped drive that the administrator does not have access to, but I’m making large assumptions up front here. The log should give us a better error if Charles’ suggestion doesn’t give us anything helpful.
