I don't know how many people out there are running S3D on Linux, but I am nearly completely blocked from even running V5 and wondering if anyone else has been through this and solved the problem. The installer appears to run fine, but the only way I can get the software to run successfully is to then run the program as root, and that is not acceptable for everyday use.
Without fail, if I don't run it as root, after I enter my credentials I get a popup stating, "Failed to activate software. The software will now exit." When I click OK, a window with what appears to be the V5 interface flashes for a fraction of a second and then disappears. I did a video screen capture and I can see the V5 window for just a couple of frames, and the title bar even says "(Licensed to .....)" with my name in it. So even though it seems to have successfully phoned home and validated my license, it just won't run as me.
I have tried nearly every combination of:
1) running the installer
a) from a root login shell
b) from my unprivileged user's login shell using the sudo command
c) as my unprivileged user; this results in a message "There has been an error. This installer requires root privileges. Please become superuser before executing the installer"
2) checking or unchecking the "Launch Simplify3D Now" box at the end of the installer (leaving it checked works, because then S3D launches as root)
3) installing to
a) /opt/Simplify3D-5.0.0
b) same as (a), then copying /opt/Simplify3D-5.0.0 to my home directory and changing ownership to my unprivileged user
4) without or without running /opt/Simplify3D-5.0.0/AddUserPermissions.sh
5) OS versions:
a) Linux Mint MATE 21 (recently installed laptop)
b) booting from multiple live images on USB stick (Ubuntu 20.04, 22.04, Lubuntu 22.04, Linux Mint Cinnamon 20.3 and 21)
6) Hardware: four computers in all, ranging from 16 to 64 GB of RAM, all with ample HDD/SSD or RAM disk space to install S3D V5
7) Authenticating my license when running /opt/Simplify3D-5.0.0/LaunchScript.sh
a) entering my correct credentials
b) entering a garbage password (displays an appropriate error message, confirming that it is talking to the S3D server(s))
I don't know what else to try.
