Hey Gene Shtirmer , going from the old method (downloading the installer and running it) to the new in rpm based installer in 3.1.10, I did the following on my setup:
Add installer repo and installer:
sudo yum install http://yum.128technology.com/installer/repo.rpm
sudo yum install 128T-installer
...then run installer:
sudo install128t
...which gave me the following versions:
[t128@ip-172-31-64-171 ~]$ rpm -q 128T-installer
128T-installer-1.1.7-0.x86_64
[t128@ip-172-31-64-171 ~]$ sudo install128t --version
128T Installer 1.1.7
