Encore CS6 hangs on file IO

It seems something has changed in Adobe Media Encoder.  I'd not tried to used Encore in months.  Yesterday I tried it.  I use Windows 10 (Feature update to Windows 10, version 1803).  It did not fail on the import step, however I did get "error code 3" when trying to build the ISO image; this was resolved by running Encore in Windows 7 compatibility mode.

I completely re-rendered everything from Premiere through AME and chose H.264 instead of H.264 Blu-Ray for the encoding.  Re-created the Encore project using the MP4 instead of M4V + WAV files and Encore successfully created the BD-R.  It had to transcode everything of course and took a long time, but it worked at least.  Have not looked into whether I notice a degradation in video quality but I will take a look at that as well as the bit rates and see what Encore did with the MP4s I gave it.  Feel I had more control using H.264 Blu-Ray from AME but that way does not work at all.

Some seemed to have same issue as me; some not.  Someone posited the issue was related to some change in Adobe Media Encoder.  I doubt Adobe even tests Encore when they update other software.  I now use Video Redo TV Suite 5 to do the audio/video multiplexing of Adobe Media Encoder output.  Back when Adobe Encore CS6 was working for me, I did not use Video Redo to multiplex because Encore wanted to re-transcode files that were multiplexed with Video Redo.

I have the same problem when encoding with Media Encoder 12.12.(Build 69). Encore CS6 is not responding when importing a m4v file (h264 Bluray, 25 Mbit VBR). When i reencode this file with Media Encoder from CC15 (same profile as used with CC18) the file can imported into encore without any problem. In end of april 2018 i was able to import m4v files to encore from Media Encoder CC18 without problems. It seems that an update of Media Encoder between end of april 2018 til mid of august causes the malfunction for encore. Is there any tweek for media encoder to encode h264 Bluray files that can imported to encore CS6

I too started having this problem.  I do not use Encore more than a few times a year.  It worked a few months ago but is not working now.  I will try the run as administrator suggestion but any new information on this problem?  In March 2017 there was a thread talking about how some Microsoft Windows 10 security patches broke Encore but mine was working in early 2018 so this was probably not my issue.

One other thing to try is Run as Administrator http://forums.adobe.com/thread/969395 to assign FULL Windows permissions may help

With the exception of Encore (updates stopped in 2012, I think), I am using Adobe Premiere Pro and Media Encoder along with After Effects with CC updates current on July 26, 2018.
