When I start a LR 5.7, I get a message "This action cannot be completed because the other application is busy. Choose "Swiotch To" to activate the busy programm and correct the problem." When I click on Switch To, it opens menu from Start button. If I click on Retry, it opens LR. How do I get rid of this message?
And what - verbatim - does the error message say?
Windows 7 64 bit.
I quoted exactly what message says in my original post.
