Installation Problems - does not contain valid signature

Sorry to hear you are having these problems. Can you please upload a screenshot of your error? I am assuming you were able to install the panel itself, but are not able to install extensions.

Also, is this the first time you are trying exchange or did this just stop working for you?

Thanks

Thanks for the screen shots. The Exchange team will look into this.

Just to confirm that you have the right versions:

1. Extension Manager 6.0.5

2. Adobe Exchange panel 0.9.4

If you have different versions,please get the latest from here:

Extension Manager :http://www.adobe.com/exchange/em_download/

Adobe Exchange: www.adobeexchange.com

I am investigating your problem.

Hello:

I don't know why this post didn't come up as a result when I was searching but I am having the exact same issue.

I created a thread already so, sorry to be redundent but thought i'd post here too to let the exchange team know i'm having the same problem.

I have checked all the same things as the creator of this thread.

thank you.

ps. here is the message i get from Norton when i try to install the Adobe Exchange panel. I uninstalled it in hopes that the new release would then install. i wish i had just left well enough alone because at least i could still be using it but then again it didn't seem to work all that well any way. eg. the Level Up game worked twice then stopped working and other extensions i wanted wouldn't download.

so, it looks like Norton is blocking it b/c it hasn't been used enough? why would Adobe release an update that hasn't been verified? just wondering.

We just bought the Transition Pack 1 from FilmImpact.net via Adobe Exchange. The installation failed in the process with the same error(does not contain valid signature). I close Premiere and restart the computer, open Premiere and Adobe Exchange and nothing, its like never happened.  Download product, no where to be found.

Hi TBTG,

Sorry to hear you've been having trouble. I've investigated your issue and I can see that we do have a record of the purchase. Your installation problems seem to have been caused by a problem with our licensing checks for the latest version of this product, but a change has been made on our end and this should now be resolved.

Can you please try installation again?

Many thanks,

Fraser

hello:

Just checking in to see if there is a fix for the Exchange Panel

please lmk if it is now working as it will save me a headache and time trying to install many thanx in advance

Hello,

The issue with Norton has been resolved.

So if you are running in a CC product then please ensure you have installed all the latest point product updates by closing and restarting the Creative Cloud desktop application (use the settings icon in the top right hand corner to exit the application). The update will download the latest version of the panel.

If you are running in CS6 then you can download the latest panel from https://www.adobeexchange.com/

Kind regards,

Lea

Thank you lesavage i appreciate the info!

Hi Sorbo86,

Are you having troubles installing Adobe Exchange or with a purchased product?

Kind regards,

Lea

Hi Lea,

I have troubles installing Adobe Exchange:

The error is: The extension "Adobe Exchange" does not contain a valid signature.

The programs are installed in Italian.

Thank you.

Andrea

Thanks Andrea,

Can you:

1) Navigate to C:\Users\<username>\AppData\Roaming\Adobe\CEPServiceManager4\extensions and delete the directory AdobeExchange

2) Open Extension and remove AdobeExchange if it is in the extensions list

3) Download the ZXP from www.adobeexchange.com and install through Extension Manager CC

Does that fix it?

Kind regards,

Lea

1) In the path: C:\Users\<username>\AppData\Roaming\Adobe\CEPServiceManager4 I can not find the extensions folder.

2) AdobeEchange isn,t in the list:

3) The extension that I'm trying to install, has been discharged from that address about an hour ago...

The problem is stil present.

Thanks

Andrea

Ok, so do you have any firewall that could be restricting a license check by Extension Manager?

If not, could you set up the following logging:

1. Create a file called 'ExManCoreLibLog.YES' and place it in the following location:
   • WIN: C:\Users\<username>\AppData\Roaming\Adobe\Extension Manager CC\Log\ExManCoreLibLog.YES
2. Then create a file named 'ExManLog.YES' and place it at:
   • WIN: C:\Program Files (x86)\Adobe\Adobe Extension Manager CC\ExManLog.YES
3. The logs files are generated and saved in the following location:
   • WIN: C:\Users\<username>\AppData\Roaming\Adobe\Extension Manager CC\Log

Then try to install the panel again. If that fails, try opening a CC point product and opening Adobe Exchange (Windows > Extensions > AdobeExchange) and attempting a self-update.

If these all fail, please gather the logs and send them to me at lesavage at adobe dot com

Thanks,

Lea

One solution, if you are running an Extension Manager version < 7.2, is to disable internet access:

In Extension Manager go to:

Tools > Preferences > uncheck Allow Extension Manager to access internet

Restart Extension Manager and retry installing the extension.

Kind regards,

Lea

Perfect, now it works!

Thank you very much

I am having the same problem on the Mac OS X flavor of the "Extension Manager CC". I was able to install the AdobeExchange panel by disabling internet access in the Extension Manager. The problem is caused by the way my company's firewall/proxy works. All https traffic is decrypted, logged, and re-signed by the local trusted CA. In order to get the Adobe CC software management tool to work in this environment, I needed to add our certificates to the Java keystore (cacerts) that Adobe CC ships in its embedded Java.

When I hit this problem in the Extension Manager, I tried to find a similar file that needed to be updated. However, I did not find one. I'm not sure how the Extension Manager manages its SSL certificates, but that is probably the problem that I'm having.

We have updated the our ZXPSign lib( which is responsible for signature validation ). Hopefully you don't need this workaround( disabling Internet access in Extension Manager CC ) anymore. The update of Extension Manager CC will be released soon.

Regarding your question about the SSL certificates management, Extension Manager does not maintain or manage any certificates. It just depends on the OS certificate library.
