I'd like to get a few log files from you to troubleshoot further. Please see the FAQ https://forums.adobe.com/thread/985831 and provide the 4 files mentioned in the FAQ (install.log, FlashPlayerInstallManager.log, Adobe_ADM.log, and Adobe_GDE.log). Please read through the FAQ first before doing anything. For the Adobe_ADM.log file, please follow the instructions to create the adm.trace file to enable verbose logging before running the installer.
After obtaining all 4 files, upload them using the instructions posted at https://forums.adobe.com/thread/1408375 and post the URL to the uploaded files in your reply.
I appreciate your eagerness to aid me, but what you ask of me is way beyond my capacity to accomplish! I’m just a retiree trying to watch some TV on my laptop. Why is this so difficult?
I have used various Macs over the years, but never had such frustration attempting to install a basic program. I am not a happy camper.

I'm sorry you're having such difficulty installing Flash Player. Please try the offline installer posted at the bottom of the Installation problems | Flash Player | Mac page in the 'Still having problems' section.
