Thanks for the link. I have seen that discussion and others like it. I don't have any older versions of any of the apps installed, only the latest PS, LR, and BR. The problem is with the Creative Cloud app itself. Three weeks ago, I spent 45 minutes in a remote debugging session with Adobe engineers from India. They walked me through a fix that involved (a) killing one of the Adobe processes that runs at startup (unfortunately, I don't recall which process it was ... there are a seven or eight of them) and (b) renaming two dll's in C:\Program Files (x86)\Common Files\Adobe\CoreSyncExtension\. Then I retried the update and it ran quickly to completion. However just as I suspected, the next time the app needed to update itself (which happened today), it again failed with error 184. I'm pretty sure the same temporary fix will work, but I don't remember which app to kill! It's most certainly one of these: FYI, the relevant line in the instal.log says WARN: Unable to move file at "C:\adobeTemp\ETRA667.tmp\7\CoreSyncExtension\CoreSync_x64.dll" to "C:\Program Files (x86)\Common Files\Adobe\CoreSyncExtension\CoreSync_x64.dll" Error 32 The process cannot access the file because it is being used by another process.. Try setting correct permissions to the specified file/folder or parent folder, so that admin has rights to modify it. Unfortunately, the message does not identify the process. Now here's how the failed update is hurting my system: When the Creative Cloud app finishes updating, regardless of whether it succeeds or fails, it kills and restarts explorer.exe. If the update has failed, CC will try to update itself again the next time the PC is restarted ... and the next time ... and the next time. The attempted update happens relatively soon after I boot the PC, while other programs are still being started. Explorer.exe is being killed while other critical startup events are still happening, leaving my system in a broken state. A possible workaround might be to delay the startup of Creative Cloud, but I have no idea how to do it.
