Update: On reflection, I decided to install 11.0.03 after all, but for some reason this comes up:
"X The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch."

I have since uninstalled this link, as it doesn't work and retained the previous version.
How do I locate tools and logs left over on my computer to delete them?
Qualys.com said that one of my Adobe downloads was out of date. Despite clicking on "Fix It", I get a message saying I have already installed 10.1.7.
However, as I go through your instructions, onto step 7 in a moment, here are the results of the OTL survey:
