Can't open downloaded app due "unknown publisher"

I can't open a downloaded app because of an "unknow publisher"

This is Apple's "Gatekeeper" which blocks programs from being installed on your computer that isn't part of AppStore enviroment or their registered developers.
The way it just blocks things kind of makes new computer users beleive only App Store is a source of software.
The way it's implemened is wrong, it should warn you that the app is from a unverified publisher and then have a button to allow it to be installed regardless, like it is on Windows.
Except Apple did things this way and now people have tons of questions and want to turn it off.
If a user needs more controls on outside software, then that should be a option in preferences, not blocking all apps by default.
So it's a blocker, not a fair warning of the higher risks with unverified developers software.
It's very uproductive for developers to spread malware, most are in it for profit or good hearted reasons and the bad ones are few and discovered in short time anyway.

  • Can't open downloaded files due to 'unidentified developer'

    Hi,
    When trying to open an application file download from the internet I get a message window that states:
    "ROES_Utility" can't be opened because it is from an unidentified developer.
    According to the reputable company i'm trying to download this from, this is due to setting on my Mac -
    I understand the reason why this is happening but what is the solution? What settings do I need to change? 
    thanks in advance,
    G.

    "Next" time it will be easy.
    But the 1st time, "Ya Just Gotta Know", and that is not so easy. 
    Glad it got you going.

  • CAN'T open downloaded app

    Hi
    I have Macbook pro, OX lion 10.7....I have purchased package for MS office from App store... its been downloaded and installed but i cant open it.... when i click onthe icon it blinks and nothing opens. any one having solution......?

    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.
    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).
    When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    Important: Some private information, such as your name, may appear in the log. Anonymize before posting.

  • Can't open any apps on my mac book pro that i downloaded from the cloud

    can't open any apps in i-tunes on my mac book pro that i downloaded from the cloud

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output andWi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • I can't open all apps I download on my iPad mini!!

    I Can't open all apps I download on my iPad mini pls help What should I do..

    Do you have enough free space on your iPad for it to run efficiently? With iOS 8 it is recommended that you have 15-20% of the storage space on the device free.  For a 16 GB device that is 2.4-3.2 GB free. For a 32 GB device that is 4.8-6.4 GB free. For a 64 GB device that is 9.6-12.8 GB free.
    Try quitting all apps and then reset the iPad. Double click the Home button to show the screen with running and recently used apps. Each app icon will have a sample page above it. Flick up on the page (not the app icon) and the page will fly away and the app icon will disappear. This quits that app. Do this for all apps that appear there. Then reset the iPad. Press and hold both the Home button and the Sleep/Wake button continuously until the Apple logo appears. Then release the button and let the device restart. You will not lose data doing this. It's like a computer reboot.

  • Getting "Can not open the file due to unknown error(FRM:0007)"

    Getting "Can not open the file due to unknown error(FRM:0007)", when refreshing the local copy of Deski report  from user docs.
    Any assistance
    Thanks,
    Sasi.

    Hi Sasi,
    One of the reason for this error is corrupted universe.So you can try following steps and restore copy of universe and then try to import this universe and check whether it works.
    1.While importing a universe, a temp file is created in the users local settings temp directory.
    2. For example C:\Documents and Settings\brijones\Local Settings\Temp\0dd0b0a7 .
    3. File has no extension is relatively the same size as the original universe file.
    4.Rename this file to original universe name.
    I hope it helps.
    Regards,
    Snehal

    Try downloading another app - any free app - that seems to reset something and the apps may start working again. Try that first. If that doesnt work, try these steps
    Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
    Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
    Close all apps. Go to the home screen first by tapping the home button. Quit/close open apps by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner to close the apps. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.

  • Can't open downloaded ibooks on iPad

    Can't open downloaded ibooks on iPad Brooks i was reading some days ago.

    You can't - ibooks from Apple can currently only be read in the iBooks app on an iPad, iPhone and iPod Touch, Apple haven't so far made a Mac or PC reader for them
    If you don't have one of those iOS devices, then though all purchases are considered final, you can try contacting iTunes support and see if they will refund or credit you : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Purchases, Billing & Redemption

  • Recently I can not open any app. in my Ipad except original ones. How can I fix this problem?

    Recently I can not open any app. in my Ipad except original ones. How can I fix this problem?

    You do NOT need to restore your iPad.
    I believe that the problem is that there is a disconnect with your iTunes account and your iPad. What you are experiencing is a somewhat common issue after you sync your iPad, update your device - it could be a number of reasons that are causing it. the recommended fix is to download another app in order to "reconnect" your ID and iTunes account to the iPad.
    You can read more about it here. You will need a WiFi internet connection in order to fix it - or you have to be able to sync with your own iTunes library.
    iOS: Troubleshooting applications purchased from the App Store
    But this is what it says in the article.
    3. Install another app from the App Store
    If none of your user-installed apps will launch, there could be an issue with Apple ID authorization. Download and install a free (or paid) app that isn't already installed on your device to reset this information. You could also remove an app from your iOS device and download it again from the App Store or sync the app from your computer.
    Note: If you have installed apps using multiple Apple ID accounts, you may need to perform this step for each account.

  • Hello, i can't open any apps on my macbook air or install any app

    Hello, i can't open any apps on my macbook air. when i am attempting it says "you may need to reinstall app but when i am trying to reinstall it doesn't do anything. i can only browse right now. It happened right after when i deleted some files i was trying to uninstall the useless app and i think i accidently deleted some system files. Right now it is letting me to download the app but i cannot install any of the app or even open any application. please help

    If you don't already have a current backup, 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.
    There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it.

  • I can't open any apps on my iPad. Everything goes back to the main menu. Anybody have a solution to this?

    Has anybody got some advice? I can't open any apps on my iPad. Everything goes back to the main menu immediately.

    Perform a Reset... Try again...
    Reset  ( No Data will be Lost )
    Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
    Wait for the Apple logo to Appear...
    Usually takes about 15 - 20 Seconds... ( But can take Longer...)
    Release the Buttons...

    Also consider Deleting any Apps you have Purchased / Downloaded but you now never use...
