LR 6 will not launch

[nancythenice]

I have the standalone version of LR6 and have used it successfully for some time.  Now, when I attempt to open the program, the title screen opens, but I get a message that "LR is not responding" when I attempt to go beyond that.  For example, I cannot even get the File button to do anything.  Would it be possible to simply reload the program?

Which version of Windows 10?

How to Find Out Which Build and Version of Windows 10 You Have

Did you do any Windows updates before Lightroom failed to start?

Have you tried re-setting your Preferences?

I think so

[nancythenice]

It is "windows 10 home"

Version 1607

Os build 14393.1358

OK, thanks.

Try re-setting your Lightroom Preferences per the steps given in the link above.

I will try that. Thanks

Sadly, it didnt work. I successfully accessed the command to reset

preferences, said yes, selected a catalogue, the opening screen appeared

but the catalogue never loaded. When I clicked on File, or Library, it

said LR was not responding. I got the sam response when accessing an older

backup catalogue, so I dont think that is the problem. I found that

several of my most recent catalogue and backups carried the lock file. It

had not apparently been removed when the program was shut dowm. But going

back to a version of the catalogue that did not have the lock file also

didnt work.
