Thank you. I renamed upgrades as you said, then did a quick repair and rebuild, as well as other rebuilds that mentioned caching in the name. I also tried another browser completely, and then just for good measure, from another computer/browser altogether. Still goes right to step 5. Does it matter if I have the old SuiteCRM-7.9.2.zip file in the upload folder? Contents of upload below.
