Installing Proto DW extension fails

When attempting to install the Dreamweaver Proto extension, I get an error message stating "The extension "Adobe Proto Dreamweaver Extension" does not contain valid signature. The extension will not be installed." Is there a fix for this?

Are you trying to install the extension with CS6? It will not work for earlier versions. If you have CS5.5 or older, use this video tutorial to get your projects into DW:

Hope this helps,

  • "extension cannot be installed because licensing verification failed"

    Hi everyone,
         I have the Adobe Photography plan for Photoshop CC, and it works perfectly fine, it will open and close normally, but when i try to install an extension, it will give me this error message: "extension cannot be installed because licensing verification failed". Please help. Much appreciated!!

    Is your extension directly downloaded from https://creative.adobe.com/addons
    If yes, Please click "Tools"->"Preferences" menu item in Extension Manager, check "Enable detailed logging" option. Restart Extension Manager. Try to install the extension. After error message promopt, send the log files under "C:\Users\<YourUserName>\AppData\Roaming\Adobe\Extension Manager CC\Log" (Windows) or "/Users/<YourUserName>/Library/Application Support/Adobe/Extension Manager CC/Log" (Mac) folder  to [email protected]

  • Adobe Extension Manager CS5 - Adobe InDesign extensions failed to import on Mac OSX 10.9.3

    Purchased a new MacBook Pro in January and just now trying to load my copy of Adobe CS5 onto it. Everything installed okay, but when I launch Adobe Extension Manager I get an error message saying that certain extensions failed to import and to make sure they are valid extensions.
    I tried to install a 3rd party extension that I use and it will not import either. Not sure if this is a software or hardware issue.
    Error message reads as follows:
    The following extensions 'idcs5_AssetPubLibrary.zxp,idcs5_AssignmentUI.zxp,idcs5_Assignments.zxp,idcs5_AWS.zxp,idc s5_AWSUI.zxp,idcs5_BasicTools.zxp,idcs5_Book Panel.zxp,....' for product 'InDesign CS5' failed to be imported. Please make sure these are valid extensions.
    I tried to update the extension manager to version 5.0.3 and that did not work. I tried uninstalling the entire suite and reinstalling and same results.
    Any help would be greatly appreciated.

    My guess is that you're trying to use the Migrate feature from OSX. Unfortunately, this will not work reliably with Adobe Creative Suite/Creative Cloud applications.
    You'll need to run the Adobe Cleaner tool to delete all Adobe stuff you copied over:
    Use the CC Cleaner Tool to solve installation ... - Adobe
    Then you'll have to install  CS5 from your original discs or a backup of your original install files.
    Lacking that, you can download CS5 from this link:

  • Installing PHP OCI8 extension on SLES 11 with PHP 5.6.3 Oracle Instantclient 12.1 and APACHE2

    I am attempting to install the OCI8 extension. The OCI8 extension version is oci-2.0.8.
    The configure script to install is "./configure --with-oci8=instantclient,/usr/lib/oracle/12.1/client64/lib".
    The configure runs ok. But when I run make test, it fails on every single oci test.
    The install directory of instantclient is "/usr/lib/oracle/12.1/client64"
    I have also declared $ORACLE_HOME and $LD_LIBRARY_PATH, and also declared instantclient in the path.
    I have also installed Perl on the server and that runs script's to update the remote oracle database. So the issue is not with instantclient.
    I am not sure what to do. Have spent 2 days on this issue. Any help will be greatly appreciated.
    Thanks.

    How and where did you set the environment variables?
    How are you running the tests?
    What errors are you seeing?

  • Error while installing Microsoft Identity Extensions Setup during installation of SharePoint Foundation 2013 on Windows Server 2012

    Hi All,
     When i try to manually (no internet connection on the server) install SharePoint 2013 Prerequisites on Windows Server 2012 I get the below error
    I have installed .Net Framework 3.5, 4.0 and Windows Identity Foundation using Add server roles or features from the server manager.
    From Software & Hardware requirements for SharePoint 2013 give
    Prerequisites for SharePoint 2013 I can see that the identity extensions are available only of Windows Server 2008 R2 and not for windows server 2012. Can you please provide the link for windows server 2012?

    I fixed it by installing Microsoft Identity extensions from command line, please find command line below.
    C:\Windows\System32>msiexec.exe /i "C:\SharePoint2013ServerFiles\prerequisiteinstallerfiles\MicrosoftIdentityExtensions-64.msi" /quiet /norestart
    Note: In the above command C:\SharePoint2013ServerFiles\prerequisiteinsTallerfiles is the path where I had downloaded all the prerequisites for SP2013
    This will install Microsoft Identity Extensions and creates registry entries, which will help the SharePoint 2013 Prerequisite installer to complete the setup

    Numerous attempts at a clean install of iTunes have failed.  I am running Win7 64 bit on a Toshiba L series Satellite w/8G RAM and 100  G HDD space.  Error message was (-42404), but following a complete (recommended) uninstall am now getting "Error 7".  The prior uninstall included the establishment of administrator rights to files and folders left in the Apple folder after running the uninstaller, and successfully removing ALL visible and hidden Apple files and folders.
    Any other suggestions out there folks?

    On Oracle Metalink site, there are many documents which says that Oracle 32 bit software works on 32 bits OS and 64 bits software works on 64 bits OS. Official support is only in those combination....
    So there is no good way to help you in your case-XE is 32 bit application with hard codded compiled libraries which most of them would not work on 64 bit OS.

  • Invalid signature when trying to install Photoshop CC extension using the Adobe Extension Manager CC and default installed Photoshop CC extensions won't load

    I have a Creative Cloud subscription for Photoshop CC. All Creative Clouds products are updated to the latest versions. When I tried to install Tony Kuyper's TKActionv3 Photoshop extension using the Adobe Extension Manager CC on my PC desktop, I received an error message that the extension contained an invalid signature and wouldn't be installed. I had previously installed the extension on my laptop without any problems. At the same time, I also noticed the default installed Photoshop CC extensions (e.g., Adobe Exchange, Kuler, Mini Bridge, Behance) could not be loaded using the Windows/Extension command. I receive an error message that the command could not be completed because the extension could not be loaded. After contacting Tony Kuyper, he suggested that I try the steps mentioned in the following weblink: https://forums.adobe.com/message/6029768. The steps basically consist of uninstalling and reinstalling all the Creative Cloud apps associated with Photoshop CC. I tried the steps multiple times, but I am still having the same problems. I can find the default installed Photoshop CC extensions on my machine, so I don't know why they can't be loaded.
    Thanks for your assistance,
    Mark Curtis

    Hi Mark
    You say everything is up to date?  And you have tried reinstalling all the CC apps?  Is Windows also fully up to date?  Hmmm...  That could be tricky.
    What version of Windows are you using?  Have a look in Task Manager > Processes and see if 'CEPServiceManager.exe *32' is listed as running?
    If not, I don't know where it would be installed from, and we'd need someone like Chris Cox to join the thread to tell us, but my guess is that it would install along with the CC Desktop Application Manager.  Windows 8.1 can be problematic, and a bit fussy about the order of things, and it is definitely worth adopting best practice when installing your CC apps.  That means restarting your computer, and right clicking the Desktop Application manager and running as Administrator.
    How many CC apps are you running?  If just Photoshop, Bridge, Expansion manager etc. then - and I hate to say this - perhaps have another go at reinstalling, but run the Cleaning tool after uninstalling.
    Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
    Try some other Extensions before the Tony Kuyper's TKActionv3.  GuideGuide is a favourite of mine, as well as Dmonzon tools, and maybe Russell Brown's Flypaper Textures. 
    I have to say that I have had problems with the CC Extension Manager a while back, but simply reinstalling just the Extension Manager fixed it.  Perhaps CEPServiceManager.exe *32 installs with Extension Manager?  Heck, maybe start with just trying that before reinstalling all your CC apps.
    If you are still stuck, I'd risk sending Chris Cox a PM, but not until you triple check that your video card driver is up to date from the card maker's website.
    Good luck, and be sure to let us know how you get on.

  • HT5381 I am running Snow Leopard 10.6.8 and attempting to upgrade to Mavericks....installation completes and a message appears stating that my computer will restart in x seconds.  I then get a message "Application install OS X Mavericks failed to quit". A

    IMac upgrade from Snow Leopard 10.6.8 to Mavericks errors by failing to restart computer........after install message states that "your computer is restarting in x seconds"...then window appears that "application install OS x Mavericks failed to quit"...try to log out again, quit install OS x Mavericks and choose apple menu to log out...........this does not work!

    Are you running OS X Server (the forum this question was posted in), or are you running OS X?  If you're not sure what that difference is and why I'm asking it, then you're probably running OS X and are very likely not running OS X Server here.
    Hopefully you have a pre-upgrade backup of your data, on the off chance something has either already gone badly wrong already, or if something goes wrong with the following...
    To force the quit here and to force the shutdown here, press and hold the power button for ~10 seconds.
    If you don't have a backup already and if the box doesn't reboot, then you'll want to boot from the 10.6 DVD (of OS X or OS X Server) and create a backup — it won't be a particularly good backup of the OS X or OS X Server system, but at least you'll have access to your own files and related data.  This backup because recovering from a badly-failed upgrade might involve reinstalling OS X.
