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.

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.

Extension does not contain valid signature

Hi all,
I open again a thread about a problem at our extension installation on several computers.
Few persons can't install our extensions. They get this message: " The extension xxx does not contain valid signature. The extension will not be installed"
Our plugins worked always since the beginning ( about December 2010 )
Our certificate is valid and has been created by TrustCenter.
I use ucf.jar with correct parameters...
I thought that's a manifest problem. So, I tried to generate plugins from Extension Builder trial version which generates manifest "automatically" but the result is the same. I also tried to get a release from a non-signed certificate ( 1024-RSA and 2048-RSA )....but unsuccessfull...
How to get a extension with valid signature for all computers ?
Thanks.
Regards.

(@harbs: already budgeted for it )
Yesterday we finalized our investigation and we now have a plan regarding the fix. Our #1 priority has been to get a working solution to customers ASAP. Here are the details:
Problem
The current implementation of Extension Manager cannot access the system root keychain on Mac 10.7.1. That is due to a particular component used by Extension Manager.
Solution
Stage 1:
We will make a manual fix available by Friday 10/28 morning Pacific time. The fix will be a .swf that end-users should download and manually replace the Extension Manager .swf on their machines. After they replace the .swf, they can go ahead and install extensions using Extension Manager. This will only apply to users who are on Mac 10.7+. In addition, your users should be running Extension Manager CS5 or CS5.5 and should download the latest update through Adobe Update Manager if they haven't done so already.
I understand that this is not optimal user experience but it is the fastest solution that we can make available.
We will post the .swf and detailed instructions on this forum thread.
Stage 2:
We are already working on an update to Extension Manager that will be available through Adobe Update Manager in mid November. The update will work even if some of your users have replaced the Extension Manager .swf on Stage 1 above (ie it will overwrite the fix from Stage 1). Only users that face this problem will be notified to download the update.
Note 1: Doing the manual fix is not necessary. You could still wait until the AUM update is available.
Note 2: The fix we do in Stage 1 is different than the one we'll do for Stage 2.
Note 3: No update is necessary for CS Extension Builder or the CS SDK.
Please let me know if you have any questions or concerns.
Thank you again for helping us in discovering and solving this issue and your understanding as we drive to a solution. I will keep you all posted as news develops.

Adobe exchange panel does not load in cc applications

I cannot launch the Adobe Exchange Panel in Photoshop or Illustrator. The option to launch this extension is not available in my menu. In Photoshop "Extensions is grayed out". In Illustrator it is not grayed out but it is simply not populated. I have tested this on my laptop and it works just fine there.
I have pasted the above paragraph from a separate thread in a different forum. I was directed to this forum by an adobe staff member.
Thanks in advance for any help with this as the forums are the only support adobe provides for this issue. I think the issue may be a corruption in my extension manager somewhere in the Windows Registry. Using Windows 7 64-bit SP1

Hi markerline,
Can I ask where you obtained Photoshop CC from? Were you part of any prerelease program?
Can you please check these folders:
C:\Program Files (x86)\Common Files\Adobe\CEPServiceManager4\extensions
C:\Users\<username>\AppData\Roaming\Adobe\CEPServiceManager4\extensions
and tell us if either one (or both) contains a folder called "AdobeExchange", and whether it contains anything.
It seems obvious, but please install any updates for Photoshop available in the Creative Cloud application. I believe there have been a few CC updates released so far - so it would be worthwhile restarting your computer to force a fresh check for updates to make sure you have them all.
Something to try would be downloading the Exchange Panel as a ZXP from here:
https://www.adobeexchange.com/
and then installing the panel using Extension Manager CC. Note that Extension Manager CS6 will not install the Exchange Panel for CC applications - it needs to be Extension Manager CC.
Let us know how you get on.
Thanks,
Fraser

PE 13 crashes due to incompatible video driver detected. Running on Win 7 SP1 with ATI 540v video card/driver. Deleting bad driver file in adobe program data does not fix the problem, it simply replaces the text file and crashes again. My video driver

PE 13 crashes due to incompatible video driver detected. Running on Win 7 SP1 with ATI 540v video card/driver. Deleting bad driver file in adobe program data does not fix the problem, it simply replaces the text file and crashes again. My video driver is just fine. Any help out there?

rb
Your video card driver may be fine for something, but just not compatible with Premiere Elements 13/13.1.
For those with the display card error, the answers include
a. assure your video card/graphics card driver version is up to date according to the web site of the manufacturer of the card -
if necessary consider a driver roll back.
b. determine in Device Manager/Display Adapters if the computer is using 2 cards instead of 1
c. delete the BadDrivers.txt file
the rationale for that deletion is found in post 10 of the following older post...principle applies to 13 as well as 9.
Re: Premiere Elements 9 Tryout Serious Display Problem
Have you looked for computer ATI card settings that might be more compatible with Premiere Elements 13/13.1?
When is the program crashing - just opening a new project or rather crashing if editing a particular video format at the Timeline level?

Adobe Reader X does not launch

Hello,
Frequently, Adobe Reader X does not start on my Windows 7 computer.
I have tried the following methods of access:
Desktop link
Start > All Program > Adobe Reader X
Run > C:\Program Files (x86)\Adobe\Reader 10.0\Reader\AcroRd32.exe
Environmental specs:
Computer: ASUS laptop
OS: Windows 7, fully updated as of 2/5/12
RAM: 8 gigs
Processor: Intel i5, second gen
Observations:
Subsequent attempts to launch Adobe Reader X add another "AcroRd.exe *32" image to the "Processes" tab in Windows Task Manager (the count of these images can build up very high).
These same attempts fail to add an "Adobe Reader X" task in the "Applications" tab of Task Manager.
The CPU and Memory were only at 25% of their capacities during the last occurrence.
[Failed] attempts taken to fix problem:
Repair install
Complete uninstall / reinstall
Workaround:
As of now, the only workaround I have found is to restart my computer. If I am lucky, Adobe Reader X will open after booting. Otherwise, I just have to keep restarting until it works.
Any help would be great.
Thanks,
Sam

Would it be possible for you to:
1. Temporarily disable the antivirus program and try launching Reader again.
2. Try launching Reader by right clicking on the shortcut and selecting "Run as Administrator"
If all the above steps produce negative results, please check the Event Logs on your machine (Control Panel > Administrative Tools > Evenet Viewer > Windows Logs > Application) and see if you are seeing any error related to Adobe Reader.
Also, could you let me know if launching Adobe Reader produces any error of sorts, or does it simply not launch inspite of a process being spawned.

Did you install plug-ins from a previous version of Photosop (or point the additional plug-ins to a previous version)? Photoshop CS6 has changed the location and way of installing plug-ins. All required plug-ins are stored internally–the location depends on the OS–and only non-Adobe 3rd party plug-ins should now be installed in the main Plug-ins folder.
You'll need to clean out and/or fix your plug-ins to get the correct behavior back...

Adobe Creative Cloud does not support Bootcamp by Apple IOS operating system, but does work with boot camp Win 8.1 why"

Adobe Creative Cloud does not support APPLE latest IOS operating system, but does allow Windows 8.1 to be accepted. This seems a shame to me, as
Apple IOS is the leader in graphics, photography. The advertising states it is usable under both APPLE IOS and Microsoft 8.1 windows operating systems. Adobe Support Chat Sooraj tells me on 02/19/2015 that i must buy two computers to have it operate on both operating systems. Adobe will not support apple's Boot CAMP allowing both operating systems.
i love the apple product and love the ADOBE Photoshop CC, but it simply does now work with an apple keyboard and a WiN operating system. .[email protected] Adobe Creative Cloud

I have a new Macbook pro, about 2 months old, and at times running video, the fans starts and does not stop. how do you get it to stop.

I have a new Macbookbook, about 2 months old, and at times running video, the fans starts and does not stop. how do you get it to stop. Also i am thinking once the video is done the fan should be slowing down and getting quiet on its own.

Your fan(s) will run at high speed (i.e., loudly) while video is playing, and you can't get around that.
If your fans are not slowing down within 2-4 minutes after CPU- and/or GPU-intensive usage ends, and the application that was showing the video is still running, Quit that application. (In fact, if you're accustomed to Windows, you may not realize that simply closing a Mac application's window does not quit the application. You still need to use the Quit command in the application-name menu. There will always be a bright dot beside or below the application icon in your Dock for each application that is open.) Quit the ones you aren't using, and see whether that allows the fans to slow down without restarting the machine. If that doesn't do the trick, reset the SMC:

It says 'error' every time I try to open it, but I am still able to attach the iPhotos saved to emails. Help! How do I get my iPhoto back?

Thanks, Sig.
The old computer is a 2.6 Ghz Intel Core 2 Duo
The new one is a 2.3 GHz intel core i7
In going over this, thanks to "tallking it out" with you, I did discover the Text Edit problem. Because I've still been unable to get the new computer text size (fonts or whatever) to match the old computer, I did not notice that the curser is now different--the line midway down the curser has to be placed on the line I am working upon, otherwise the edits go elsewhere on the page. Now, with a bit of difficulty, I am able to get Text Edit to work correctly.
If you have any ideas as to why my menu bar and Text Edit type are still so slow, I'd love to have them.
(I went through the process you suggested earlier, re my Trackpad preferences, and found no improvement.)

Hello farahani hairon nizar,
If your Apple ID was changed from your old account, you may have to change it back to your old account to be able to sign out and then change it back after that is done. Take a look at the article below for more information.

C# compiling error: 'System.Array' does not contain a definition for 'Select' and no extension method 'Select' accepting a first argument of type 'System.Array' could be found (are you missing a using directive or an assembly reference?)

Hello experts,
I'm totally new to C#. I'm trying to modify existing code to automatically rename a file if exists. I found a solution online as follows:
string[] allFiles = Directory.GetFiles(folderPath).Select(filename => Path.GetFileNameWithoutExtension(filename)).ToArray();
string tempFileName = fileName;
int count = 1;
while (allFiles.Contains(tempFileName ))
tempFileName = String.Format("{0} ({1})", fileName, count++);
output = Path.Combine(folderPath, tempFileName );
string fullPath=output + ".xml";
However, it gives the following compilation errors
for the Select and Contain methods respectively.:
'System.Array' does not contain a definition for 'Select' and no extension method 'Select' accepting a first argument of type 'System.Array' could be found
(are you missing a using directive or an assembly reference?)
'System.Array' does not contain a definition for 'Contains' and no extension method 'Contains' accepting a first argument of type 'System.Array' could be
found (are you missing a using directive or an assembly reference?)
I googled on these errors, and people suggested to add using System.Linq;
I did, but the errors persist.
Any help and information is greatly appreciated.
P. S. Here are the using clauses I have:
using System;
using System.Data;
using System.Windows.Forms;
using System.IO;
using System.Collections.Generic;
using System.Text;
using System.Linq;

Besides your issue with System.Core, you also have a problem with the logic of our code, particularly your variables. It is confusing what your variables represent. You have an infinite loop, so the last section of code is never reached. Take a look
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
namespace consAppFileManipulation
class Program
static void Main(string[] args)
string fullPath = @"c:\temp\trace.log";
string folderPath = @"c:\temp\";
string fileName = "trace.log";
string output = "";
string fileNameOnly = Path.GetFileNameWithoutExtension(fullPath);
string extension = Path.GetExtension(fullPath);
string path = Path.GetDirectoryName(fullPath);
string newFullPath = fullPath;
string[] allFiles = Directory.GetFiles(folderPath).Select(filename => Path.GetFileNameWithoutExtension(filename)).ToArray();
string tempFileName = fileName;
int count = 1;
//THIS IS AN INFINITE LOOP
while (allFiles.Contains(fileNameOnly))
tempFileName = String.Format("{0} ({1})", fileName, count++);
//THIS CODE IS NEVER REACHED
output = Path.Combine(folderPath, tempFileName);
fullPath = output + ".xml";
//string fullPath = output + ".xml";
