The extension does not contain a valid signature

hey guys, newbie on deck!
So, after installing CS6 I ran the Adobe Update Manger. During the update the Adobe Extension Manager (AEM) fired off and began updating as well. One error I saw was:
The extension 'Adobe_Flash_Professional_Toolkit_for_CreateJS' does not contain a valid signature. The extension will not be installed.
I'm not sure what this is or what it does but I would like to:
Understand the Adobe ecosystem and
Clear any problems.
Here's what I do know:
The Mac I have is 2 days old and probably in the best shape of its life.
I installed CS6 fresh from a DVD.
Ran the Adobe Update Manager the next day (today).
I don't intend to use Flash.
If anyone can expain common causes for this behavior and a fix I would greatly appreciate it.
Thanks in advance,
TT

Hi JesusPresley,
The root cause is the updater updated Adobe Flash, which tried to install the extension above by Extension Manager in the installation. However, this extension was NOT signed with the updated Adobe certificate, so the extension installation will be rejected by Extension Manager. That is what you got. We have sent this issue to Flash team.
If you don't use Flash, you can manually edit C:\Program Files\Adobe\Adobe Flash CS6\XManConfig.xml, and remove the line <Data key="SupportedInSuite">CS6</Data>. Thanks.

  • Old/Bad Extension Manager 5.5 on Adobe Exchange- Extension does not contain a valid signature

    The Adobe Exchange Download page has an old version of Adobe Extension Manager that fails on Mac OS Mountain Lion and later. Anyone who attempts to download Extension Manager gets this old version, 5.5.0.163.
    BAD - http://www.adobe.com/exchange/em_download/em55_download.html
    Version 5.5.3 is available from the following link, but Adobe search and download page link to the exchange download, not this link.
    http://download.macromedia.com/pub/dw_exchange/extension_manager/mac/AdobeExtensionManager _5_5_3_mul_AdobeUpdate.dmg
    Adobe, Please update the link so that we can a little more easily download a version that doesn't show the misleading error "The Extension does not contain a valid signature. The extension will not be installed".

    Sorry for that. We listed the old version in that page because the latest 5.5.3 patch can be installed ONLY AFTER you have installed the old version. Actually you can find the product updates at http://www.adobe.com/downloads/updates/. Also you can launch Adobe Application Manager or Creative Cloud app to learn which products are updatable and update them if necessary.

    Try creating a new Flex project and dragging the files from
    the zip into the
    src folder. You may find that you need to rearrange things a
    bit, depending
    on how they set up the project, but this should get you
    started.

  • WDS "The file does not contain a valid install image"

    I have WDS installed on a Windows Server 2008 R2 SP1 machine.  I can quite happily import Windows 7 Install images from the Windows 7 installation DVD, but if I try to import from the Windows Server 2008 R2 SP1 installation DVD, at sources\install.wim, I
    get:
    "The file does not contain a valid install image"
    If I run WDSUTIL from the command line I get:
    "An install image could not be found in the image file".
    I believe that the DVD is fine as I can install machines from it and mount the sources\install.wim file using DISM.
    Anyone any idea what's wrong?
    Note that the problem is not with my own images, it's with the image as supplied on media direct from Microsoft.

    Which download link did you use to get your SP1 media? From this link:
    http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=5842 ?

  • The extention does not contain valid signature...".

    Hi
    I made .ZPX file. But during unpacking it shows an alert "The extention does not contain valid signature...". What can be reason and how to fix it?

    Hi Maxim3,
    It is difficult to tell what is wrong with your ZXP without inspecting what's inside it, but here are a few things which could cause this kind of error in Extension Manager
    Adding files to the ZXP after it has already been signed
    Adding a whole folder to a ZXP, rather than the contents of a folder (since Extension Manager won't find your MXI in the root level of your ZXP)
    Adding files which contain double-byte characters (e.g. Traditional Chinese)
    The command should have looked something like this:
    java -jar ucf.jar -package  -storetype PKCS12 -keystore cert.p12 -storepass password outputfile.zxp -C "/inputfolder" .
    [note the dot (.) at the end of the command]
    Probably the easiest way to package a ZXP is using Adobe Exchange Packager:
    https://www.adobeexchange.com/api/Packager.exe
    https://www.adobeexchange.com/api/Packager.dmg
    ...as you can use this to create self-signed certificates, and it guides you through the process of packaging and signing.

  • SCCM 2012 - Adding Operating System Installer (The specified path does not contain a valid operating system ..)

    I have encountered the dreaded "The specified path does not contain a valid operating system or you do not have permission to access it.  Specify a valid path" message that seems to be popular in many forums .... BUT, so far none of the "solutions"
    have fixed the problem (of I don't understand the fix)
    Configuration
    SCCM 2012 SP1 5.0.7804.1000
    WADK 8.100.26629.0  < Suggested Fix
    Server 2008 R2
    SCCM Administrator with UserID = SCCMAdmin 
    Steps / Fixes I have followed
    I have configured a administrative share
    \\caleb\sources$ to hold directories (such as Apps, Drivers, and OS) with the following NTFS Permissions
    EVERYONE has Read and Execute, List folder, Read permissions<o:p></o:p>
    SYSTEM has Full Control 
    <Suggested Fix
    SCCMManagers (our group that has all SCCMManagers) has Full Control<o:p></o:p>
    SCCMAdmin (the SCCM Admin account that we are using to import image) has Full Control<o:p></o:p>
    Local Administrators (the local machine administrator) has Full Control 
    <Suggested Fix
    <o:p></o:p>
    Another Fix is to explicitly grant all permissions to the SCCM Administrator
    <Suggested Fix
    >Administrative Users ...
    Properties of the SCCM Administrator (for us that is SCCMAdmin) has all the boxes checked<o:p></o:p>
    Another suggestion I was able to glean was to Specify the Network Access Account
    so I configured SCCMAdmin as the Network Access Account.
    Another potential fix is that the image ISO file that has been downloaded is corrupt.   So, I downloaded the Win 7 (and Win 8.1) ISO's from MSDN and did a Checksum check.
    I then mounted the ISO (on 2008R2 I use VirtualClone Drive) and copied the contents of the image to
    E:\Sources\OS\en_windows_7_professional_with_sp1_vl_build_x86_dvd_u_677896 for Windows 7 with SP1
    To double check,
    I computed the Hash on the Install.WIM located in the Sources directory and compared with
    the computed Has Tag for the Install.WIM on the ISO Image  ... and the Hash tag of the WIM's matched (extracted vs what is contained within the ISO)<o:p></o:p>
    I tried to load the images into SCCM 2012 using the "Operating System Installers" option
    UNC to installer
    \\caleb\sources$\OS\en_windows_7_professional_with_sp1_vl_build_x86_dvd_u_677896
    Then I receive the lovely message <o:p></o:p>

  • The specified UNC path does not contain a valid WIM file or you do not have permission to access it. please specify a valid path

  • MDT 0xc0000098 The windows boot configuration data file does not contain a valid OS entry

    hello,
    i installed WDS+MDT for OS deployment. all was working fine.
    Now i need our branch office to be able to deploy OS as well.
    I installed a new Win 2008R2 server, and installed the WDS service on it.
    When reading about this on the internet i saw i need, on the MDT at our main office, to make a link, under "Advanced Configuration" - "Linked Deployment Shares" to the new WDS server (I used this: http://www.balm.se/?p=115")
    when doing so i entered the UNC path to the new server and then, on the created link, i right click and choose "Replicate now".
    after doing so, i tried booting a laptop just to see if there is any impact, and now, I'm getting this error:
    Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
    1. insert your windows installation disk and restart your computer
    2. choose your language, and then click "Next"

    For a branch solution I would use DFS(R) rather than linked deploymentshares.
    If there is infrastructure at the remote sites you could use the MDT environment at your main site, and  then at each other site use an existing server or build a new server (VM is available). Create a Deploymentshare on each sever
    and copy the contents of the MDT environment from the first site into this share.  Next you will have to add the WDS service to each site's server. For WDS add the boot image. Of course as Keith noted ensure that you
    have the same versions of MDT and the WAIK/ADK on all systems
    You can use DFS to replicate to all of the other sites, but you will still have to create a deploymentshare, and install WDS at each site. So each site talks to its own WDS server you can use the DefaultGateway parameter instead -
    [Settings]
    Priority=Default, DefaultGateway
    [Default]
    SkipBDDWelcome=YES
    [DefaultGateway]
    192.168.10.1=Bergen
    192.168.20.1=Oslo
    [Bergen]
    DeployRoot=\\MDT-Bergen\DeploymentShare$
    [Oslo]
    DeployRoot=\\MDT-Oslo\DeploymentShare$

  • Imac-- Upgrading elements 10 to elements 12. Did successful backup of 10.  When restore to 12 message said the disk in drive My Passport for Mac does not contain a valid backup

    IIMac      doing upgrade of Elements 10 to Elementys 12.  Did full backup of 10 on my external hard drive "MY Passport".  Rec'd message backup successful.  Did restore on 12 and rec'd message "The disk in drive My Passport for Mac does not contain a valid backup".  Any help suggestions?

    The funniest part of the whole situation, Apple Care explained it to me as some kind of feature. The told me how to adjust the time when my computer sleeps and recommend I don't shut it down, let it sleep and "instant wake". I would bet if you called them about your Macbook, they would suggest you just close the lid and let it sleep rather than shutting it down.
    Basically shutdown and restart have a problem and the solution is to not shutdown is how they explained it to me. They kept saying buzz words like "instant on" and "fast wakeup". My computer already could sleep and wakeup fast, but now shutdown and restart don't work right. I called them 3 times about it, but since they use these buzzwords, sounds like Lion is meant for a Macbook Air or a Mac with an SSD. If you have a normal hard disk, some of the saving/versions/resume features take too long to be written to the disk on shutdown. And when you start again, it takes a long time to reload the system to it's previous point.
    Even if I uncheck the box to reopen windows on next start, it reopens them anyways.
    If they can't give me a better explaination or some kind of fix, I will have to go back to Snow Leopard. I use my Mac in a production environment and depend on stability. They assured me before I upgraded that it would be stable and all the new saving and versions features could help my productivity. So far it's not helping me and downright annoying. You need to close all your windows before you close the program... if you have 5 windows open in terminal or textedit... every time you launch, they will launch all those windows. I just really want versions, not resume it seems.
    But I can deal with it opening a million windows, just can't take it getting stuck on booting or not shutting down properly. This is a "feature" that should be fixed. LOL

  • Project does not contain a valid connection problem

    I am using JDeveloper 10.1.3.2.0 and have checked out code that was in CVS. I tried to put the code under an Application and Project, but when I do the check out, the Application Navigator shows it at the Application level. Within that Application, there are two projects. When I do a Make on either project, I get the error that The Business Component Project does not contain a valid connection. Double clicking on the error send me to the corresponding .jpx file which contains this:
