How to run Embroidery Studio Digital Edition offline/without the internet?
Each licensed copy of EmbroideryStudio is for a single user.
You may
install it on multiple computers but only one active session can be used
at one time.
On the Sign-in dialog, tick ‘Keep me signed in’ and you will
not have to re-connect to the Internet for 20 days.

The Export Machine
