I purchased AVG for multiple PC's but it will not let me download to my desktop which is Windows Vista - says I need to upgrade to Google Chrome but OS will not let me and indicates it will not support.  I have a laptop with Windows 10 and have successfully completed the download.  Is there a way I can download internet security to Windows Vista without purchasing a new CPU?
