Why does not open Lightroom?

Trying to open Lightroom, I get the pop up box telling me that "Lightroom cannot use the catalog named 'Catalogue Lightroom' because it is not writable and cannot be opened".  Then he said: "this could be caused by incorrect permissions or because that another Lightroom application uses the catalog.  You can try to fix the problem, or you can select a different catalog. "Usually, I restart the PC and it opens then, it sometimes takes two or three re - start.  However, I restarted six times, and I get the same message.  On a forum that I went, the Council is 'delete the .lock file '.  I searched on the PC and I a. lock.file.  Should I remove it?  What is the solution?

Just to let you know, this lock file is normally removed when Lightroom closes if it closes normally. If something happens during the shutdown process to avoid a normal stop this lock file may be left.

  • Why does not open ADE 4.5 in Windows 10?

    When I click on the desktop icon, I get a cursor for a few seconds, but no window ADE appears.  I checked the Task Manager and no application ADE is active.  I uninstalled and reinstalled ADE several times and get the same result.  I have an ASUS transformer CHI T100 computer with operating system Windows 10.  Before I upgraded to win 8-10, I could open ADE and activate it.  So maybe that's why I get no error windows.  Other that the cursor occupied at all nothing happens when I try to run ADE.

    Any ideas?  I use ADE mainly to transfer eBooks from my computer to my Nook reader.

  • Lightroom 6.0 does not open

    Hello, I bought Lightroom 6.0 in 2015 Dec (not membership of the creative cloud - just the application). I have used it very well, but do not have the last couple months. When I go to open the application, the wheel just keeps spinning with Lightroom front page showing version 6.0. Nothing happens and the application does not in fact. I thought to uninstall but don't know if I can re - stall it now. I know there have been a few updates to the 6.0 version, but because the application does not open, and I can't actually click on anything on the top tool bar of Lightroom, I don't know what to do. Help, please! Thank you.
