I eventually found that the old icon on my desktop was launching adobe Lightroom 5.7( the old version)...
I had assumed the Lightroom version launched by the icon on my desktop was 6.1 after I had done my upgrade but that was not the case....
(I'm not sure, why this icon was not cleaned up during the upgrade from 5.7 to 6.1....). I have to confess that I did not read any instructions for the upgrade-maybe this was a part of the instructions?
When I finally launched Lightroom 6.1.1 and then upgraded the addons; I was finally able to import the Sony raw files for the new A7Rm2.
However I now have to uninstall the old Lightroom 5.7 which did not uninstall during the upgrade process from 5.7 to 6.1.
I am now removing it via windows using- control panel-programs-uninstall.
I can see the two versions (new and old) reported as installed....
Thanks again for the help......
Are you an adobe service representative?
Your welcome robertlue. Yes, I am an Adobe Representative.
When you install the upgrade version Lightroom 6, it does not automatically uninstall the previous version.
Previous versions remain unaffected there and you get two versions of Lightroom after the upgrade and that is why your Lightroom 5.7.1 was still there after installing Lightroom 6 upgrade.
