HCL are now using InstallAnywhere for Domino installations. This is a change, but many of the screens will be pretty much the same.
One thing to note is that there no longer appears to be a GUI option for installing Domino on Linux. I have found that for customers who insisted on getting that working that it was alway, umm, “fun” making sure everything was in place. I tended to install via console/command mode anyway. Then you should still be able to do Remote Server Setup from your workstation.
Also, make note of the change to from setup.exe to domino.exe.
Finally, the default paths for new installations changes from having IBM as a path name to HCL.
