Update, 13th March, 2020:
For legal reasons, we can no longer offer the ASE license as a separate downloadable .rar. Therefore, the best option is to upgrade to 7.52 SP04 which is valid until 31st March 2021, and transport your work via abapGit. https://blogs.sap.com/2017/06/21/abapgit-so-easy/
Note: Since we now have 6 blogs referring to 2 different versions of the download developer edition, blog comments are becoming unmanageable. In addition, searching through blog comments is very difficult for other users, resulting in many duplicate issues.
From now on, please DO NOT post a blog comment if you require troubleshooting.
Please post on the ABAP Development forum:
using the hashtag #ABAP_Trial.
In case of Linux problems read the Linux FAQ.
Thank you for your understanding.
I apologize for the inconvenience.
