I have downloaded OSGeo4W 64-bit from https://qgis.org/en/site/forusers/download.html and would like to do a 'bleeding edge development build" on my Windows 10. So I select clicked Run and selected Advanced Install, install from internet, set root directory, direct connection, chose the download site, then it gets to the Select Packages stage.
I click Next and immediately get an Installation Status that says "OSGeo4W installation completed successfully" at the top and "Nothing needed to be installed" at the bottom with the Finish button. I have looked around and QGIS isn't installed. What am I doing wrong?
