You need Volume Shadow Copy on for Persona Management to Work. Also, You will want to set the Loopback Policy to enabled. Honestly, you don't want to run EVRYTHING in that script all the time, especially on newer versions of View where the Windows Firewall has to be on for Blast to work. I left a link for the Persona Guide as well a link to the Flings OS Optimization Tool. It has a GUI interface instead of the script. I think It really helps you better see what is happening, you can customize and create your own config, and roll back. The site is messed up right now. But the link should work eventually. Wouldn't be the first time a VMware page was down.
