Lightroom won't open on my mac

I am attempting to activate Lightroom on a mac. I've used it on this computer in the past and it suddenly stopped working. I deleted the file and installed the product again. The installation went through, but Lightroom won't open. I tried deactivating the product before deleting, but there was no option. What am I missing?

What happens when you try to open Lightroom?
What is the error message?
What version of Lightroom?
What operating system?

Lightroom won't open, says it's open in another application?Lightroom won't open, says it's open in another application?

Lightroom won't open, says it's open in another application..

Depending on your operating system, use Windows Explorer or Finder to open the folder containing your catalog. In that folder you will find a file with the same name as your catalog, but with the .lock extension. That file needs to be deleted, and then you will be able to start Lightroom.

Loaded 5.7.1 now Lightroom won't open

loaded Lightroom 5.7.1 now Lightroom won't open?

I just upgraded to 5.7.1 and get the same on OS X 10.10.1. The messages is
Adobe Photoshop Lightroom 5 cannot be opened because of a problem.
I tried deleting Lightroom and reinstalling, just the same.
I tried deleting the preference file in $HOME/Library/Preferences/com.adobe.Lightroom5.plist
again crashes just the same, and Lightroom crashes before recreating the file.
Tried a reboot. No joy.

Just installed Lightroom 4.4 and now Lightroom won't open.

I have been working with Lr 4.3 and just upgraded to 4.4. Now Lr won't open when I click on the icon. How do I fix this?

I have copied this from another post I made in the forum see if helps you.
When Lightroom is open it creates a file with the same name as the catalog with an extension .lock (LOCK) alongside the catalog file.
This lock file prevents any other access to the catalog.
If Lightroom is closed normally the .lock file is automatically deleted. However if Lightroom closes unexpectedly e.g. loss of power, crash then the file may remain in place preventing Lightroom from opening the catalog.
With Lightroom closed go to the folder where your Catalog files reside, by default this is in your User > My Pictures> Lightroom. If there is a .lock file present delete the file (do not delete the .lrcat file. See the screen capture.
If you have found a .lock file and deleted it, then double click on the actual Catalog file and see if it opens Lightroom.

My iTunes won't open help please! what should I do?

My iTunes won't open, when I try to open it, it says:
"The file 'i Tunes Library.itl' cannot be read because it was created by a newer version of itunes."
What can I do about this? please help me.

Ps.. My quicktime opens and I can search for music and play it but itunes still wont' open
thank you kindly.
another couple of preliminary questions aimed at narrowing in on possible culprits.
(1) do you have Norton Internet Security 2005 installed on the PC?
(2) reboot the PC. bring up your Task Manager, and click on the "Processes" tab. now try to launch itunes again.
does an "itunes.exe" process appear in the Processes tab? if so, does it persist in there or does it disappear after a few seconds?

Itunes won't open - help!

I have been using itunes for 3 months without any problem and for the past week it will not work. The problem I am getting is when I double click the itunes shortcut, sometimes an egg timer is displayed for 10 secs, then nothing. On other times, I manage to get the itunes licensing agreement on screen. I have tried everything to get it working - I've clicked on save, then agree. I've clicked on save, then disagree but itunes still won't open. I have read through the support section on the itunes website and carried out the following:
1. uninstalled & reinstalled itunes
2. uninstalled & reinstalled quicktime
3. run windows clean up to uninstall itunes & quicktime
4. rebooted PC so many times and wasted so many hours!
I am now at a complete loss at what to do next. I still have the same problem - itunes icon is on desktop but nothing happens when I double click. Can someone please please help?
Thanks
Jackie

hi Jackie!
When I open up Task Manager, itunes application is running and I can't kill the process without rebooting my PC.
usually i associate that "running itunes.exe process That Will Not Die" symptom with nasty version of the NIS 2005 itunes launch suppressions ... but you've got McAfee ...
let's quickly check up on a possibility that can also result in you seeing a running itunes.exe (even though itunes silently fails to launch):

My Safari was updated to 5.1.9 and now it won't open - help!

Safari updated itself a few days ago and was working fine up until this morning. Now I click on it, it bobs up and down once or twice, but a browser window won't open. Any suggestions for what I can do to fix it??

Ideally - locate a crash report from Console application... look in Diagnostic & Usage Information - User Diagnostic Reports in the log list on the left & see if there's one for Safari dated today. If so, copy it & paste the contents here.

Lightroom Won't Open - Activation Just Loops

Would greatly appreciate some expert help with this. I've tried to use Adobe Chat, but have been kept waiting for hours without any response.
I purchased the boxed version of Lightroom 3 from Adobe some years back, installed it on my iMac. It was working at one time, though I did not use it much. (I also purchased CS5.5 creative suite, parts of which I use all the time.)
Recently I tried to open Lightroom 3 but the program wouldn't open. It asked me for my serial number. So, I entered it and filled out the registration (again), and tried to open the program. Clicking on the icon only brought up the window asking if I want to buy the program or else enter the serial number. So I repeated the process. Same result. Click on the Lightroom icon and the same window pops up, asking for the serial number.
I can't get past this loop.
Can anyone tell me what steps to follow in order to get Lightroom working again?
Thanks in advance for your help.

If no one suggests anything better, or the problem clears up, my best suggestion would be uninstall and reinstall. This should be a fairly quick operation, and it won't affect your catalogue.

Lightroom won't open - I get an error message....is open in another application.....It isn't and I can't progress from there. It allows me to open a different catalogue such as April 2015 but that has only 2 photo's in it ? Any suggestions ?

Can anyone help ?

1. Open Windows Explorer (Windows) or Finder (Mac).
2. Open the folder that contains your Lightroom catalog.
3. In that folder, look for a file with the .lock extension. If your catalog is named Lightroom 5 catalog.lrcat then the file will be named Lightroom 5 catalog.lock.
4. If you find such a file, highlight the file and delete it. You do that by pressing the delete key.
5. Close Windows Explorer or Finder.
6. Start Lightroom as you normally would.
In case you don't know where your catalog is located, if you are using Windows it will be located in Pictures\Lightroom. I'm not sure what the path is for the Mac.
