I installed Developer Hub Trial Org 64-bit Windows option.
I created a trial project with: 
     sfdx force:project:create -n geolocation

But, when I try to create the scratch org with:
      sfdx force:org:create -s -f config/project-scratch-def.json -a GeoAppScratch
I get this:
     ERROR running force:org:create: You do  not have access to the [scratchorgiinfo] object

I've tried several suggested fixes that I found when I searched for the above error. None has resolved the issue for me.

Working through the "Get Ready to Create an App" trailhead module and I'm stuck on the step to create a new scratch org.
I keep getting this error:
          ERROR running force:org:create:  You do not have access to the [ScratchOrgInfo] object.

I'm using the copy function of the text snippet so I know it's not a syntax problem.
                sfdx force:org:create -s -f config/project-scratch-def.json -a GeoAppScratch

Anyone run into this?
