Siemens S7 Manager no license found.

When you boot up the computer, wait until the "Automation Lisence Manager" is up and running.
Then launch Step7 Manager.
If for any reason you have disabled the "Automation Lisence Manager" you won't be able to run Step7.
 
You can use the "Automation Lisence manager" to scan your hard drive (C:)
and find the Lisence(s) in case you messed up at some point.
 
have you newest license manager installed
older manegers losted license sometimes at 64bit environment, rebooting pc showed license again
