If you have the engine .zip you should go to Menu>Software>Master repository
Then chec in Package and then select the Package that you have downloaded then you need to select evaluation branch
By the way, the engine will be included in todays DAT
Just to clarify and to avoid any potential confusion, that's with the dat, not in the dat.
The engine and dat are separate objects for download.
It's a small, but quite important distinction
Follow below link and download engine package for ePO console.
Check in that package into ePO console under : Menu>Software>Master repository as suggested by llamamecomoquieras
Have you had a chance to Check in the ePO Engine package to your master repository and test?
If you have could you let us know how it went and if this resolves your query.
Yes this is all working now and in my master repository.
Thanks for the help.
If you could mark as 'answered' so other can benefit from your question that would be great.
