1) download the program and crack from above
2) disconnect internet!
3) install True Image, close installer (don not start True Image!)
4) wait about 20 seconds while background tasks still work
5) run ActivatorAcronisTI(H).exe
if you read "activation successful!" everything is ok
6) reconnect internet and have fun...

Run activator in every account if you have more than one users
(If using the initial 2017 version)

If True Image should ask for activation:
Run Activator again
