The Patch Installer will use whatever contents it needs from that folder. You will probably then see a folder called 'Payloads', but you don't need to do anything with that.
Click to do so and let it unzip in place. You will probably be told that the files need to be unzipped first. Once the download is complete, open the folder it's in and double click AdobePatchInstaller.exe But the same info is available elsewhere.) (Optionally download the associated 'Release Notes', if you want them. and last update Adobe will offer for LR6. Pick which you need, then you'll probably want 'Lightroom 6.14', the latest and greatest.
Now scroll down to 'Download Photoshop Lightroom 6' but only click on the arrow to the left, which will open a long list of the updates with the newest at the top (and full versions in the boxes). If you already have a licensed copy of LR6 that you just want to update, instead go go to THIS PAGE (which Adobe has done a great job hiding). STOP! You don't want to install that unless you want to purchase a subscription in order to activate and use it. If you search the Adobe site for Lightroom 6 updates, they will try to install LR CC or LR CC Classic. If you, like me, have tried to keep your LR6 up to date, but had trouble finding the update, here's some info I got from the Lightroom Queen that appears to work.
