Ola,
Thank you for the enquiry. While we did have a version of MyEclipse (MyEclipse 2015) which would help users continue projects started with MobiOne, we had to discontinue this support, and support for all mobile tooling due to several reasons that are mentioned in the following note:

Some suggestions on how to move forward are provided as well, do take a look and let us know if we can assist further.
You can download the latest MyEclipse 2018 installer from here and give it a try : https://www.genuitec.com/products/myeclipse/download/
Hope this helps.
