I can't seem to find the original version of Machine 2. I need it to install it on PC. Any help
You should be able to install it from Native Access if it's registered to your account. Does it show in Native Access?
Its version 2.17.4
You can find Maschine 2 legacy installers for older OS at following site:

You will also need a suiting Native Access version to activate your copy.
The latest in Native Access should be 2.18.4 - what happens when you try to install it ?
