Linux installation error going through wizard

Hello,

When I am installing matlab and going through the wizard, once I choose the installation file I end up getting this error. I looked at the link to solution ID 1-661QJD and it doesn't seem relevant to my issue (link at the bottom). I had this work a couple days ago but accidentally deleted matlab, so I have to do a reinstall. I had this issue last time and didn't know how it got fixed, just seemed from deleting everything and trying again sometimes works and sometimes doesn't. Also, I noticed when I installed a couple days ago everything was a locked file (can't delete) but this time it isn't locked. I am installing it in the home directory in a file called "Matlab". Last time I just installed it in the home directory, and learned the hard way what rm -r does in the linux terminal.

Error -2,007: Unable to activate your machine. The activation process cannot detect a valid Host ID which utilizes a currently supported naming convention. Please refer to the following solution ID, to help resolve this issue: 1-661QJD

I should add that I get this in my linux terminal with the error Gtk-WARNING : Error loading theme icon 'gtk-ok' for stock: Unable to load image-loading module: /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-svg.so: /home/rick/Matlab/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by /usr/lib/x86_64-linux-gnu/libicuuc.so.55)
