When I try to start Firefox, I get a message that it is already running but not responding and I can't run another Firefox at the same time. I uninstalled and reinstalled. No change. Tried various other suggestions. Help!!

When I try to start Firefox, I get a message that it is already running, but not responding and that I should close it before trying to run another Firefox. But I cannot find a way to close Firefox program that is not running as far as I can see. I tried uninstalling and reinstalling Firefox, but that did not work. I've tried various other things, but no luck. I thought programs should stop when the computer is turned off, but that didn't work either.

How are you opening the Profile Manager?

I am having troubles, when I open LR I get a message that there is an error and it will try to fix the error next time it opens, but I get the error next time it opens, and this is going on and on where I can not use LR, any suggestions?

I am having troubles, when I open LR I get a message that there is an error and it will try to fix the error next time it opens. LR closes on it's own, I reopen it and get that same message next time it opens, and this is going on and on where I can not use LR, any suggestions? If I click on a different set of photos in the libary before I get that message I might or might not get the message next time it oipens, but I still can not get to those photos, and it is not just one or two but most of my photos. HELP!!!!
Thanks

The first thing I would suggest is for you to go to the folder containing your catalog, using your system browser. There will be a folder that has the extension .lrdata. Delete that folder, and then try to start Lightroom. If that doesn't work, replace your catalog with your most recent backup.

When I open Muse, I get a message that a new update is available. When I hit install it just closes and nothing happens. Then I got a message I needed Adobe Creative Cloud App to resolve the issue. I downloaded a copy of Creative Cloud desktop but it says that my Muse is up to date. It was last updated in May but you have a new update today and it will not update. I thought maybe I am not suppose to have the Creative Cloud update because all I have is the individual app Muse and the photography program. So I uninstalled the CC desktop. Then when I open Muse it says I need the CC desktop to help with the update. So I get stopped either way. Now I also had a Pre-Release Muse on my computer and I don't know if that complicated things. Please advise.

All future installs/updates of Muse (and most other Adobe apps) are through the Creative Cloud desktop app. Thus you do need to have it installed.

Upgrade iTunes to the latest version. It should be 10.5.3.

I was at Apple Store yesterday and they created a pages document for me. When I got home and tried to open it, I get a message that I need a newer version of Pages. I see the image when I before I push "open". The 'kind' is pages publication.

Just be careful with Pages 5, it is not strictly an upgrade.
Apple has actually removed over 90 features and some work can be very difficult in the newer version.
It was all done to make it more interchangeable with the inferior iOS version:

When trying to open lightroom I get a message that says, "The lightroom.exe that the short cut refers to has been changed or moved, so the short cut will no longer work properly. Do you want to remove this short cut? The program has opened and worked fine in the past.

You have (probably accidentally) moved or deleted the Lightroom program. You need to find it (have your operating system search for lightroom.exe) and move it back to where the shortcut expects it to be.

A misleading and malicious popup. Launch Safari with the Shift key held down; if that doesn't work, temporarily disconnect the computer from the Internet.

Since I downloaded Apple's latest operating system, whenever I try to open Illustrator I get a message that I need to install legacy Java SE6 runtime and to click "more info" to do this. When I click "more info" I get a blank window. What should I do

Since I downloaded Apple's latest operating system, whenever I try to open Illustrator I get a message that I need to install legacy Java SE6 runtime and to click "more info" to do this. When I click "more info" I get a blank window. What should I do

Hi,
I had the same problem after upgrading to Yosemite. Illustrator CS6 wouldn't open. I got a message saying I should 'install legacy Java SE6 runtime'.
The link didn't work - it lead to a blank page.
So I downloaded Java8 (latest version) from Oracle but didn't install it. Something told me this was not the right way to go (the problem was with Java SE6, not 8). I then called Apple (in the Netherlands, were I live) for help. I got none. The best they could do was blaming Adobe for the problem or me, for not having the latest Adobe CC app. Rubbish.
And then, magic. I tried to open Illustrator again, got the pop up message but this time the link worked. It took me to an official Apple page, with a link to download Java for OS X 2014-001. The problem is now solved.
If curious, this is the explanation Apple gives for the problem:
'Java for OS X 2014-001 includes installation improvements, and supersedes all previous versions of Java for OS X. This package installs the same version of Java 6 included in Java for OS X 2013-005. On systems that have not already installed Java for OS X 2012-006 or later, this update disables the Java SE 6 applet plug-in. To use applets on a web page, click on the region labeled 'missing plug-in' to download the latest version of the Java applet plug-in from Oracle.'

After years of no problems I can't print photos. When I select print I get the message "There are no themes located. Until at least one theme has been installed this feature will be unavailable. What are themes? How do I install them?

After years of no problems I sddenly can't print photos. When I select print I get the message "There are no themes located. Until at least one theme has been installed this feature will be unavailable. What are themes? How do I install them? Why has this problem suddenly arisen?

Re-installing does not affect your Library in any way. You don't delete it, only the app.
To re-install iPhoto
1. Put the iPhoto.app in the trash (Drag it from your Applications Folder to the trash)
2a: On 10.5: Go to HD/Library/Receipts and remove any pkg file there with iPhoto in the name.
2b: On 10.6: Those receipts may be found as follows: In the Finder use the Go menu and select Go To Folder. In the resulting window type
/var/db/receipts/
2c: on 10.7 they're at
/private/var/db/receipts
A Finder Window will open at that location and you can remove the iPhoto pkg files.
3. Re-install.
If you purchased an iLife Disk, then iPhoto is on it.
If iPhoto was installed on your Mac when you go it then it’s on the System Restore disks that came with your Mac. Insert the first one and opt to ‘Install Bundled Applications Only.
If you purchased it on the App Store or have a Recent Mac you can find it in your Purchases List.
