App Store can no longer be opened. Immediate crash and error message "App Store can not be opened because of a problem"

App Store won't open, error message "App Store can not be opened because of a problem". I haven't been able to update anything for a week or so. I have used Disk Utility, Drive Genius, deleting the .plist, all to no avail. My Mac Mail hasn't worked since the upgrade to Mavericks. Mavericks can't see my LaCie Cloudbox. Can any of these be solved by me?

I have the same error "XXXX App cannot be opened because of a problem". And I also cannot open iTunes and get the error "This copy of iTunes is corrupted or is not installed correctly. Please reinstall iTunes."
Only Apple apps seem to be at issue here...
Repairing Permissions did not fix this.
I noticed this after the last Software update. Is there no fix other than re-installing?
Not happy that an Apple software update killed all my apps...

Thanks Andy,
I wish I could have told my sister about this as she could not open my homepage back before my new iWeb site. She now can open my site without the yet in case denial window does appear = I thank you.
I think my iWeb site works as Noone has said otherwise from any platform etc...

I do agree that should not have to be a consideration for any users so i agree that it would be great if Apple could allow simplicity to run seemlessly.
I have had this problem since Homepage, and here is
what has worked for me. I send out the link, and
then for PC users I send the link with "<" after the address (without quotation
marks. e.g., <http://site.com>).
I also put a note that if that doesn't work, to just
copy and paste the link into a browser. With that I
have only had 1 person say they still can't open.
Everyone else gets it to work.
It's a lot to do and seems like a hassle, but you get
used to it.
Hope this helps!
Andy Martini
PS - APPLE! When are you going to fix this??! It
seems like such a small thing yet you guys have been
stumped for YEARS on this!

""Install Adobe Flash Player.app" can't be opened because... not downloaded from the Mac App Store"

I jsut upgraded to 10.9 and it is up to date and also my safari is up to date (no updates available for it). My safari is saying that my flash is out of date. when I follow the links it lets me download but when I double click to install it tell me "“Install Adobe Flash Player.app” can’t be opened because it was not downloaded from the Mac App Store.". When I install the flash UNinstaller and try to install that, it tells me the same. I ALSO found the exact same problem when I tried to install the acrobat installer (some tried to download a pdf and the page told me that my acrobat reader 'might' be out of date). Any thought?

You're running up against the GateKeeper.
Download the offline installer: Flash Player 12.0.0.44 (Mac OS X) by right clicking and choosing "Download Linked File As".
Mount the DMG and when it opens, right click the installer and choose "Open".
You'll see a warning. Click "Open" again.
It will run from there.

While the iTunes app is being updated, you are correct, it cannot be opened.
This is true of all Apple apps on your Mac.
iTunes is not very large compared to other apps. Let it update, then open it.

I cannot open my Itunes? I keep getting this message: "The Itunes app could not be opened. An unknown error occurred. (-50) Help! I have also tried to uninstall and reinstall, but get the message that ITunes.msi cannot be found.

Why am I getting this message when I try to open my ITunes: "The Itunes app could not be opened. An unknown error occurred (-50)."?

These errors are typically resolved by performing one or more of the steps listed below:
Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting.
Put a USB 2.0 hub between the device and the computer.
Try a different USB 30-pin dock-connector cable.
Eliminate third-party security software conflicts.
There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. Your default packet size being set incorrectly can cause this error. Contact the manufacturer of the software that installed the packet-size modification for assistance. Or, follow this article by Microsoft: How to reset Internet Protocol (TCP/IP) to reset the packet size back to the default for Windows.
Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online.
Try to restore from another known-good computer and network.

Illustrator CS5 re-install error: Install.app can't be opened.

Hello everyone,
Has anyone ever seen this error when installing Illustrator CS5 on Mac OS X Lion?
"Install.app" can't be opened. You should eject the disk image.
Things that might be related;
a) I've recently upgraded the hard disk. I restored everything from a TimeMachine backup
b) I had a few strange things happen with illustrator over the last few months. Yesterday I couldn't place .png graphics into a file, so I uninstalled everything and decided to reinstall from scratch.
c) My downloaded source (illustrator_15_1_LS1.dmg) was kept on a network volume. I assumed the error meant it was corrupted so I downloaded the source again from Adobe. I get the same error on the newly downloaded file.
d) Following a suggestion elsewhere in the forums, I tried Disk Utility > Verify Disk on my new hard disk. It found several permission errors which I let it fix. The problem remains.
I'd appreciate any suggestions on how I can solve this.
Many thanks
Steve

Solved
Short answer: OS X 10.7.4 (or maybe before) introduced an incompatibility between Illustrators install file and Mac OS X.
Updating to OS X 10.7.5 solves this.
Through this post on stack overflow:
http://stackoverflow.com/questions/11171246/why-does-os-x-10-7-4-want-me-to-move-my-app-to -the-trash
it directed me towards Gate Keeper functionality of OS X 10.8 having been enabled in updates in OS X 10.7.4(or earlier, not too sure).
Running `sudo spctl -a Install.app/` gave the result CSSMERR_TP_CERT_REVOKED but the solution posted on stackoverflow of disabling gate keeper didn't work. So I set off to find a way of inspecting the certificate. I didn't find instructions to read the certificate but that did lead me to read the apple site about gate keeper and that although it was introduced as a feature in Mountain Lion (os x 10.8) some features were provided for developers in Lion (10.7).
I thought I'd have to buy and install Mountain Lion but found that I hadn't got the latest Lion update. I downloaded that, installed, restarted and now the installer works fine.

My problem is after updating to Yosemite does my mail client any longer. I can not even open the mail, and when I "forced closes" mail and try to open it again to go in the entered settings running the colored wheels around and allows me only to forcing close again? does anyone have a solution to the above problem?

You mean the default OS X mail app? Try reinstalling OS X Yosemite if that's the case.
If you are referring to 3rd party mail applications, that's a compatibility issue. Some apps don't work in the new operating system. You have to wait until the developer updates the app, or you have to revert back to Mavericks to continue using it.

Finder.app Can't be Opened after upgrade

I just upgraded to Yosemite and my desktop will load for a few seconds before disappearing and Finder.app Can't Be Opened
2014 MacBook Air

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter the name of the crashed application or process. For example, if Safari crashed, you would enter "Safari" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Select the messages from the time of the last crash, if any. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
☞ The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ User Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of crash reports. The name of each report starts with the name of the process, and ends with ".crash". Select the most recent report related to the process in question. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a crash, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

I have just installed Mountain Lion and received a message that "speech Synthesis Server.app could not be opened because it is damaged or incomplete", please advise me what to do now.

I have just installed Mountain Lion and received a message "speech synthesis server.app could not be opened because it is damaged or incomplete", please can you advise me what to do next? Thanks

Something went wrong with your upgrade.
Back up all data, then reinstall the OS. You don't need to erase the startup volume, and you won't need your backup unless something goes wrong. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it.

"Install" can not be opened

I downloaded Adobe Design Standard CS 5.5 and when trying to install it an error message came up saying: "Install" can not be opened because it is from an unidentified developer". I've downloaded it twice to check, but it keeps giving this problem.
Anyone had this issue?
Thanks!

Time machine problem? The application Finder.app can't be opened -10810

I've got a Snow Leopard system with an external FireWire Maxtor drive that has been set to be a Time Machine archive of the internal drive. I'm noticing the following problem (twice so far) which may or may not be TM related. I leave my machine and come in the morning; Time Machine says no backup happened since 7:45pm last night. I notice the file system is acting weird - can't open any of the disks from the desktop. I try to restart the Finder, and it says "The application Finder.app can't be opened -10810" - won't start the Finder! So, I had to reboot (and disconnected the FW drive). I'll try it for a couple of nights without the TM machine and see what happens. The reason I suspect TM is that sometimes I see the icon on the TM disk change from the blue/gray TM icon back to its native FW disk icon, and sometimes I see a message that says "Can't find disk" or something similar for that external drive.
Any ideas? Should I be looking for an external drive from another vendor, or will it be the same thing? Does TM have problems associated with Finder and error -10810? How do I debug?

No, I tried different drives, and it made no difference.
In the end I turned it off, and did backups with SuperDuper!.
funny you should mention SuperDuper. When you had this problem, did you have SuperDuper scheduled to back up other drives? I have a theory, which I'll test eventally. For some reason, this TM problem only happened at night - not all the times it activated (every hour) during the workday. Why?!? Well, one thing that happens at night for me is a scheduled SuperDuper backup of the same drive (the one TM is backing up) onto a mirror drive (not the one TM is writing to).
Maybe that's when the freeze occurs - when they both coincide at night? I'd think that the Unix-base of OS X shouldn't have any problems when two apps are reading one disk and at the same time, but maybe TM and SuperDuper are both doing some sort of low-level reads that can't be done at the same time? What do you think - might this explain your issues also?

When I try to launch iTunes is says that the application can not be opened

When I try to open iTunes it says that the application can not be opened, that the required folder can not be found. On my husbands log-on iTunes will open. I am so confused. Please help!!!

Hello Keaton44,
I recommend taking a look at this article named iTunes: Finding lost media and downloads found here http://support.apple.com/kb/ts1408
If you need to re download the movies you bought from iTunes you can do that free of charge with this article.

The application "Finder.app" can't be opened. Anyone getting this error after upgrade?

Upgraded to new OS version and getting "The application “Finder.app” can’t be opened."
The icon in the tray has a small black dot under it. Not sure whether that is relevant

Hi ..
A Safe Mode boot deletes some system caches that may help after an OS X upgrade.
Top left corner of your screen click the Apple  > Shut Down.
After your Mac shuts down, wait 10 seconds, then press the power button.
Immediately after you hear the startup tone, hold down the Shift key. You should press the Shift key as soon as possible after you hear the startup tone, but not before.
Release the Shift key when you see the gray Apple logo and progress indicator.
Once you are in Safe Mode, go back to the Apple  menu. From the drop down menu click: Restart
Then try the Finder.
About Safe Mode.
