On Mac OS only I have encountered that issue too.
Again, engineering needs the logs to investigate.
Do let me know the log numbers when you send them to asupport in the final step!
I am now trying to migrate our custom installer using WiXToolset on Windows that relied on ExManCmd to UPIA and I am running into an issue when a batch file being run during install just hangs after issuing the command to remove previous extension:
C:\Program Files\Common Files\Adobe\Adobe Desktop Common\RemoteComponents\UPI\UnifiedPluginInstallerAgent>UnifiedPluginInstallerAgent.exe /remove "com.cinemagrade"
Removing com.cinemagrade
As you can see, I get the message about extension being removed but no resolution and no status.
The same bat file works fine when ran from the command-line.
Installer is in the elevated mode.
Any thoughts/suggestions?
A bit late to the party, but UPIA --install gives me Request failed with status = -641 as well, and I should be logged on in the CCD (at least thereās my ugly face in the top-right corner)
Iāve tried to pass around a test ccx that doesnāt belong to the CC Marketplace, and the person wasnāt able to install via double-click. Nor with right-click, Open With, UPIA (āThe document ā¦ cannot be opened, CC cannot open files of this typeā).
UPDATE: A restart seem to have solved for them!
Surprisingly, I tried myself a couple of times and while the double-click always worked, Open With didnāt (always). When the CCD was running it seemed to be ineffective. But then I restarted and it went fine. ĀÆ\_(ć)_/ĀÆ
So in the end they have solved, and I have discovered that I canāt run UPIA 
CCD 5.9 ships with UPIA 1.6.0.34 which should clear up some of the -641 errors. Iām working on a list of updates to share, (but was sidetracked by MAX).
Iām creating installers using Inno Setup / Mac Packages and have run into some issues for our UXP plugins. Iām wondering if anyone has run into similar issues and figured out how to solve them.
Mac:
After installing using UPIA in scripts of the Packages installer, the plugin shows up in CCD under Manage Plugins, but the ellipsis menu is disabled so the user canāt uninstall it from there. If I try installing the plugin by double-clicking the ccx file, it will install fine and have the ellipsis menu enabled with an Uninstall option. What causes the uninstall option to be disabled?
Win:
I got the plugin to install using commands in the Inno Setup file but the plugins donāt show up in CCD until the computer is restarted, even though they do show in InDesign or Photoshop. After a restart of the computer, I see the plugin listed but, similar to Mac, the ellipsis menu is disabled.
Is it configured so that if you install via UPIA, you must uninstall through UPIA? That doesnāt sound like a good policy IMO.
I realize this is an old thread but the topic is good. If thereās a newer one we want to move this to, go for it.
Iāve noticed the same issue, when installing via UPIA tool. Donāt know how to overcome it.
I was able to uninstall via UPIA only and also encountered another issue:
- I install same plugin for multiple Adobe hosts
- I didnāt find a way how to uninstall plugin for specific host, I can uninstall by name of plugin, but it is the same for all hostsā¦
- so I just run command multiple times, until I remove it for all hosts
@Sir_Ivan YES! I have this same issue too, regarding each host using the same ānameā of UXP plugin so we canāt uninstall a specific one.
