@Cynthiad66 The issue is clear if you read other posts in this thread. Users including myself tried installing TT 2020 (in my case it's Home&Biz edition) and get a message from the installer that your PC does not meet minimum memory requirements (2048MB). Mine has 4GB and I already had TT installed and running on my same computer. Only when I tried to check for / install the latest online updates did I encounter the problem. Other users in this thread say they had much more than 2GB RAM - I think one guy said he has 16GB. In my case I was sure to shut down all other apps, including browser etc. before doing the install. I also ran memory diagnostic to ensure that my memory is all functional.
