Sandra refuses to run - licensing issue

It is likely you are using the software in a manner that does not comply with the licence.

For example, the Lite and Pro/Home version does not run on domains; the Pro/Home is licensed for home/personal use as per licence (paragraph 4) (http://www.sisoftware.co.uk/index.html?dir=licence&location=licence_pro_use)

"This software is not licensed to be used in a business environment including but not limited to the use on a machine that is part of a Windows Domain"
