SoftRaid will not load

I cannot get SoftRaid to load. I've tried both 6.3 and 7.0.1 (fully removing the program each time as below) and get the following errors:

With 6.3:

" SoftRaid 6.3 is trying to install a new helper tool" then after I enter my password nothing happens 

and with 7:

"SoftRAID 7.0

 

I followed these steps to fully remove the program:

Delete the SoftRAID driver:
sudo rm -r /Library/Extensions/SoftRAID.kext
sudo touch /Library/Extensions
sudo kextcache -fu /

Now, Restart your computer

Remove the daemon and SoftRAID Monitor:
sudo rm /Library/LaunchDaemons/com.softraid.softraidd.plist
sudo rm /Library/LaunchAgents/com.softraid.SoftRAIDMonitor.plist

Remove the SoftRAID application support directory:
sudo rm -r /Library/Application\ Support/SoftRAID

Remove all the SoftRAID preferences:
defaults delete com.softraid.SoftRAID

Remove preference files
sudo rm -r com.softraid.com

reset the extensions caches:
sudo kmutil clear-staging
sudo kextcache -i /

Restart the Mac. SoftRAID volumes will no longer mount on the desktop, but that is temporary, until you reinstall the driver.

When you run SoftRAID to install the driver, do not immediately restart. wait until the dialog box pops up to go to System Preferences/Security. "Allow" OWC as an Identified developer, now restart, (you have to maneuver around a couple different restart buttons SoftRAID and macOS)

Having removed all traces of the program, I cannot get the volume to mount but I can't install the program either.

How can I fix this?
