Why the Adobe Extensions Manager?
Patrick at MEI suspects the problem we are having with InCopy CS6 complaining about the missing plugin is related to the Adobe Extensions Manager CS6. Why did Adobe made extension management so complicated?
After trying many combinations we discovered that if a layout was created from scratch, an article attached to it won't throw the annoying missing plug-in dialog, but when we examine the article in InCopy it notes that this plug-in is missing. If we detach the article from the layout and open the article again in InCopy, the missing plug-in status is now empty.
To view this information on Mac OS X check out an article from K4 and then press command key while selecting About InCopy... from the InCopy menu. You should see a dialog.
We see the missing plug-in listed here. What is odd is that in some circumstances we will see the plug-in listed as missing but not get the obnoxious dialog.
After a bit of exploration we found that Adobe Extensions ManagerCS6 would complain about bad plug-ins for InDesign and InCopy. Extensions Manager was complaining about bad native plugins, not the K4 plug-ins. We duplicated this problem on a Mac that had InDesign installed without the K4 plug-ins. We tried various magics, such as launching ID as the admin user and performed various incantations. Nothing worked. Patrick had seen this issue at other sites. We are hoping that once we fix it the annoying dialogs will disappear.
Current thinking, or superstitions, is that you should install ID or IC from an admin account and then run it from that admin account and then run Adobe Extensions Manger from that admin account before allowing a non-admin account to run these programs. More testing should show if this is superstition or truth.
In any event, proper installation of ID and IC seems to be more complicated that it should be.
