I recently installed the trial version of the Adobe Media Encoder CC 2017. I imported a comp from After Effects CC 2017 and I tried to render it, but I got an error saying " Could not read from the source. Please check if it has moved or been deleted. " (the file is not moved or deleted)
After I did some research I saw that other users had the same error, the suggested solution was to get the plugins located in This PC > Local Disk (C:) > Program Files > Adobe > Common > Plug-ins > 7.0 > Medicore and move them over to the after effects plugins folder located (in my case) in This PC > Windows (C:) > Program Files > Adobe > Adobe After Effects 2017 > Plug-ins.
I tried this but it did not work and I keep getting the same error message.
Here are links to the video & the thread that were suggesting this solution:
