Topic: can't install Photoshop Templates

the Adobe extension manager complains that the package (photoshop templates) has an unverified signature and won't install the templates. I am on OSX10.8.5, running Photoshop/Extension manager CC. any ideas?

Re: can't install Photoshop Templates

The new ZXP Juicebox template for Photoshop has been signed with a valid certificate and has been tested so I am unsure what may be causing the problem you are experiencing.
Looking through the Adobe online forums, it seems that some other Creative Cloud users are experiencing similar issues with other extensions. For example, here and here.
There may be a bug in Adobe Extension Manager and the author of another extension whose users have reported a similar issue seems to think that this is the case. (Please see this forum thread.)

Make sure that your version of Adobe Extension Manager is up to date and try the advice in this forum post to see if it helps.

Please note that you should still be able to install the Juicebox template manually by downloading the ZIP version for CS2/CS3 and following the instructions on this web page.
