Going through stackoverflow, strange and crazy though, yes I have VS 2017 installed before this db engine. I still dont understand why VS2017 should be 30GB though, with a 6MB file in b4j you have a multi-platform app building IDE, even with the libraries its still a perfect solution. I guess I will always fail to understand some of the login in Microsoft things. Lol.
Decided to delete all 'Microsoft SQL Server' under program files. Phew, now I can get my ABM app ready for MSSQL use, rather frustrating journey here. Had to download a file unlock and delete app. Thanks
