I downloaded sbt 1.1.4 but why was sbt 0.13 installed?

Question

I downloaded sbt 1.1.4 msi for Windows from the scala download page.

I ran the msi. After typing sbt about, sbt downloaded all the required files. When i ran sbt about, it said the version is 0.13

Answer 1

short answer

might be best to go to Users/You/project/, delete everything and put a new build.properties file there with your desired sbt version before trying to install.

more detail, in case it helps someone

I had a similar problem. I'd updated sbt to 1.2 but when I uninstalled and tried reinstalling with the 0.13.7 installer, it would only install sbt 1.2 again. All of my projects had sbt.version=0.13.7, but I didn't realize (though it's obvious why) that there was a C:/Users/Me/project folder with version set to 1.2.

I deleted everything from that folder, put a new build.properties with the desired version, and then the 0.13.7 installer worked as expected.

Answer 2

As I answered to a similar question (adapted):

Most likely, because you have a file project/build.properties with the 0.13 version.

So one thing is the version of the launcher that you installed and another is the version of the sbt you launch in particular project. If you don't set it explicitly in project/build.properties, sbt will try to run its own version (launcher's, i.e. 1.1.4 in your case).
