I just tested now, if i go Tools - Preferences and disable BOTH "Show warning when installing unsigned ZXP extensions" and "Allow Extension Manager to connect to the Internet", it does then install and not give the signature error and installs. This done through the Extension Manager
The problem now comes with me having to deploy this via SCCM to 50 + users. This needs to be a silent install, with no user interaction required.
Thanks for the quick response.
The extension should not be unsigned but Extension Manager does require online access to complete license checks.
Is there no way to have it install the extension silently? Also, what url does it do the licensing check with? as it would then need to be added to the proxy exceptions.
The issue then seems to be that the Extension Manager is failing to connect to the licensing site, thus showing that the signature is not valid.
I can confirm that you will require to be connected to the internet when completing an Adobe Exchange update however you should not need to interact with Extension Manager. In usual circumstances, the Adobe Exchange update will be downloaded and installed when running inside the application. Extension Manager is only required if the initially attempt at installing the update has failed.
I hope this helps.
Hi there, just an update, i have found a way to resolve the issue.
Issue was trying to install the CC version of Exchange Panel. When trying to install via the command line, it would give an error that the cert was invalid.
By chance i tried to install via the Extension manager as with CS5, but this failed. I then saw there was a ExManCmd.exe
Installing the ZXP extension for Exchange Panel has now resolved the issues faced. Exchange Panel now added to all applicable apps.
Command run from command line
C:\Program Files (x86)\Adobe\Adobe Extension Manager CC>ExManCmd.exe /install C:\AdobeExchange.zxp
