I don't remember the details offhand, but it's surely in the doc: http://www.adobe.com/devnet-docs/acrobatetk/tools/Wizard/overview.html (find the Wizard X PDF at the bottom). You should also do the following:
- Read about CS/Acrobat installs in the admin guide
- Refer the CS doc for details about deploying Acrobat X that was delivered as part of that suite.
- Verify you are using the correct version of AAMEE.
I do know for sure that you can accept the EULA and disable registration.
I believe what's X supports with respect to activation is described here: http://www.adobe.com/devnet-docs/acrobatetk/tools/AdminGuide/licensing .html#activation-workflow-details.
