Try running Lightroom as an Administrator. Right click on the icon and select "Run as administrator"
Yes that worked. But that is the only way LR opens now, does not open by simply clicking on the program icon and that should not be. Adobe or windows need to release a corrective update. Thank you.
Yes I thought so, it seems to be an issue with users especially if you have no local admin and use a microsoft login, i.e. where you use a email address for login. Probably that Windows 10 thinks it is a Internet application ... you can test it by opening the Control Panel going to System and Security, then Security and Maintenance then select Windows Smartscreen on the left-hand column and change the selection to 'Warn before running and unrecognized app but don't request administrator approval'
If then it allows you to run with just a warning it is tied up in the UAC (User Account Control) settings.
