Can't run Comsol 6.0: Could not load SWT library, no swi-pi4 found

I'm trying to run Comsol 6.0 Multiphysics on my pc. It seems this software runs with Java. When I enter into

/usr/local/comsol60/multiphysics/bin/

, and then run

sudo ./comsol multiphysics

I get from the console:

grep: warning: stray \ before =
grep: warning: stray \ before =
grep: warning: stray \ before =

ERROR: Failed to start COMSOL. For details, see the log file /root/.comsol/v60/logs/comsol5.log

        Can't load library: /root/.swt/lib/linux/x86_64/libswt-pi4.so

I

sudo ls /root/.swt/lib/linux/x86_64

in order to look which libraries were installed and found:

libswt-pi-gtk-4763.so  libswt-pi3-gtk-4763.so  libswt-pi3-gtk-4932r18.so  libswt-pi3-gtk-4944r26.so

And if it's useful, the complete log: https://0x0.st/HJJm.log

I think the problem is that I should somehow install libswt-pi4 (because as I see, I guess I have libswt-pi3) but I don't know in which package comes included. Besides, I tried the steps posted in https://bbs.archlinux.org/viewtopic.php?id=278891 but had no changes. Does someone have any suggestion?

Why on earth do you run that as root?
