Hi froman007,
Welcome to the Sony Community!
I would suggest uninstalling the program again. Restart the computer, then disable the firewall and antivirus software of your computer. These may block the download of the software. Reinstall PlayMemories Home.
If you're still having issues installing it, you can also download the program without internet connection.
