Hello,
The HPE MSA Advanaced Data Services E LTU is not the license but contains the passcode needed to get a license. You need to follow the steps in the email to use the code and your HPE Passport to get a license.
HPE License Portal: http://www.hpe.com/software/entitlements
HPE Software License Activation Quick Start Guide: https://softwaresupport.softwaregrp.com/documents/10180/14684/sw_license_activation_quick_start_guide
The license will be sent to you in a certificate.txt file. Once you get the certificate.txt file, try the installation procedure again.
Cheers,
Shawn
