Some apps say "The application " " cannot be opened" ?????!?!?!?

Ok, about 20% of my apps when clicked on now give this message, only since the last time I turned the phone off and then back on. What is going on? I get a blue pop up box saying this when I try to open these apps. Tried hard restart, ect nothing works!

This happened to me after I installed the 2.1 update. The suckiest part is that you have to delete each app that does this from the phone and re-download them from the apps store. What a PITA!

Why is when I try to download from the App Store, it says "The application cannot be downloaded." I do have an ID account and my software has been updated.

Hello there, I'm new to the Apple world, and I'm still learning my way around.
Why is when I try to download from the App Store, it says "The application cannot be downloaded."
It doesn't ask me for payment or anything. When I click on download, about 10 seconds later, that message pops up and nothing is downloaded onto my laptop. I can download other stuff onto my laptop for e.g. Microsoft Word and other various programs such as Google Chrome from the internet. However, I just cannot download from App Store. Any suggestions on how I can download apps?

There is nothing wrong with my iTunes, is more of the App store that I am concerned about. And I've tried the "Authorise this computer" yes it does download when using iTunes, but no luck with App Store. And, yes I am logged onto iTunes when doing purchases.
I find this really fustrating because the App store works fine on my ipod but once it comes to my macbook, it does not download. A few seconds later after I click on an app to download, the pop up message notifies me that the purchase cannot be downloaded.
Anyways, thanks for your suggestion.

I can no longer access a password protected Numbers file with the correct password. Error message only says the file "cannot be opened."

I'm using Numbers version 3.2.2.
Suddenly I cannot access my password protected Numbers file with the correct password. I have the correct password written down so I know I haven't made a mistake.
The response box that pops up says that the file cannot be opened. There are no other options for me to choose from.

Also, I tried to open it through an older version of Numbers but it sent this error message.

Hello,
your file is probably corrupted. If you do not have a backup of this file, and if https://discussions.apple.com/message/16132821#16132821 does not help ; you can send your file to me, I will try to see if there is a chance to open it or if it is definitively lost...

I recently had my account expire, and need to utilize the trial to finish a project. Even though my account says 'free trial' the applications will not open. How do I get the APP to recognize that I'm in trial and not expired?

I had a year long CC membership that expired at the beginning of the October.
After realizing that, I attempted to start a free trial of photoshop to work on a project. My Adobe account states that i'm on a trial, but my (Mac) dashboard CC app won't allow me to start the program. I have reinstalled both Creative Cloud and Photoshop CC but still get this message.

Many 3rd party apps that I have used before now will not open with the alert "XYZ application cannot be opened because the identity of the developer cannot be confirmed" Why now?

I cannot access my folders and when I click on Finder, it says "the application Finder cannot be opened" then a number 10810. HELP!

After shutting down and rebooting, I find I have no folders on display on the desktop and when I click on the Finder icon, a message comes up that says "the application Finder cannot be opened" followed by the number 10810. HELP!

You could do it by cloning. I have read OSX installations of a single version can be machine specific too, so even if this were a Tiger compatible drive a clone might not work. I haven't seen anybody actually state a specific case where they had problems on a machine compatible with the OS version because of this though. The last case I can recall of system specific installations was back in OS7 days with system enablers. I have moved Tiger between machines by moving the drive with no problems, but the machines were pretty similar models (both Quicksilver, just a year difference production model).

This problem has been reported a few times. The solution is to install any new App say a free one. This seems to fix whatever has gone wrong.

Updated today and cannot open my mails it says: The last time you opened Mail, it unexpectedly quit while reopening windows. Do you want to try to reopen its windows again?

Do a backup.
Quit the application.
Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library. Then go to Preferences/com.apple.mail.plist. Move the .plist to your desktop.
Restart, open the application and test. If it works okay, delete the plist from the desktop.
If the application is the same, return the .plist to where you got it from, overwriting the newer one.

I have been running Firefox on my PowerPC G5 for years and have just tried to install 4.0. When I attempt to start Firefox, a window opens telling me the application cannot be launched. I have installed it twice with the same result. What gives?

I have a PowerPC G5 quad core Mac with a pre-intel chip. I have been running Firefox successfully for over five years and have used every version in operation during that time. Tonight, I received notice that the latest version of 3.6 was ready to install and that I needed to restart. I did that and was taken to a page telling me that 4.0 was available for downloading and use. So I downloaded the new 4.0 and tried to install it in the typical Mac fashion. After clicking on the dmg, I dragged the icon into my applications folder and onto the dock. But when I click on the icon on the dock, I get the message: The application cannot be launched. 10661
When I try to launch by double clicking in the applications folder, I get the message: You cannot open the application Firefox because it is not supported on this system.
I had to go to your site using Safari of all things! I tried re-installing it with another download, and that one misbehaves in the same way. By the way, in case it matters, I still have 42 GB available on my hard drive and 5 GB of RAM.
There is one other funny thing. The Firefox icon from the disk image has a white circle with the slash through it on top of the fox and world symbol. That is what appears in my applications folder and in my dock. It appears to be saying NOT FIREFOX, as it would indicate in a NO U-TURN sign. What is this all about?

I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

I keep gettin updates from my app store but yet when I go in and update all it starts the update and then pops up and tells me that the application cannot be downloaded at this time. I have had to delete a few apps bc this isn't working.

I keep getting updates from my app store but yet when I go in and update it starts the process but then a message pops up that says the download cannot be done at this time. I have had to delete a few apps because of this. I have also signed out and signed back into my account and turned my phone on and off and still does the same thing. Help!

Hi tmcrae
First check that your device is not full, maybe you may have to delete some photos or apps to make space to do updates. if its not full then you will have to try pluging it into your pc/mac running itunes then doing a backup and restore. Then you should be able to do your updates.
Sorry but i cant think of any other way if its showing as installed already but is not there.
Hope that helps

Thank you for clarify I'm supposed to read the ENTIRE article. I thought I was just supposed to read the title and magically everything will fix itself. I appreciate you taking the time to help me however I do not appreciate the caps and the way you have addressed the situation. If you are not going to kindly help people/make suggestions just don't try! And for the record my conclusions are not illogical, the iOS7 thing is on the website in small font (which I got by reading the ENTIRE thing) and you should really find a new hobby because your socialization skills need some help! That goes for you too Chris. Not everyone is a tech nerd

Could you see whether Firefox will start in its Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
Here's how:
With Firefox closed, hold down the Shift key while starting Firefox.
A small dialog should appear. Click "Start in Safe Mode" (''not'' Reset).
Does that work?

Cannot move any files into trash to delete them. I get a Trash warning box saying "The Finder cannot complete the operation because some data in 'file name' could not be read or written.(Error code - 36)".Macbook has so much data it is almost not working

Cannot move any files into trash to delete them. I get a Trash warning box saying "The Finder cannot complete the operation because some data in 'file name' could not be read or written.(Error code - 36)".Macbook has so much data it is almost not working.
I have tried reseting to factory settings by removing battery and holding down the power switch for more than 5 sec but this does nothing.
Any ideas would be greatly appreciated as I think with so much unwanted data on the desktop and other places the whole os will crash very soon.
Thanks, Rick

The hard drive may be dying anyway, or the directory damaged because it is so full. You should never let the hard drive get over 85% full.
A -36 error is a read/write error.
All you did with the power is reset the SMC. Does nothing to reset everything to factory settings.
Do you have your original 10.4 installer discs for the MacBook?
Is your data backed up?
