I have just installed Lightroom 6.1.1. When I synchronize folders it tells me there are (say) 12 more files to import.

When I click OK I get this

dynamiclinkmediaserver has encountered an error.

[/DynamicLinkMediaServer8/releases/2014.03/shared/adobe/MediaCore/ASL/Foundation/Src/DirectoryRegistry.cpp-283]

and it fails to import. Ideas?

I get the error when opening Lightroom CC. Since the last update, I think? I'm too busy to try to get rid of it and all the complaints say nothing works anyway. Strangely I'm seeing folks talk about this in several places but nowhere any response from Adobe. Nada. Anyway once I click OK everything seems to work normally. I just hate that damn popup.

I have gotten the same error message since starting to use lightroom, 2 versions ago, and it continues.  I have never been able to use video in lightroom, or the slideshows. You are right, I have spent hours and hours researching this and tried to contact Adobe about it but they just are no help whatsoever.

Two thoughts: 

1) User account/permissions issues. Have you tried running from a new Admin user account?
2) A 3rd party conflict interfering with communication with DLS. Have you tried running in SafeMode?

Jeffery - thanks for the reply.  The problem is definitely #1.  I should have mentioned that when I started Lightroom fresh on my laptop, there was no issue.  When I started from another Admin user account, I get a fresh - but empty Lightroom with no issues, problem solved - but - I also can't get access to my 25000 photo collection in my original Lightroom file.  So the question remains - how do I fix this on my existing data file without having to start fresh and lose access to my extensive previous work?  Also, if I start as new admin user, all my apple iCloud settings and syncs will be messed up because it won't recognize the new user.

Nope - I did the manual permissions change, rebooted, still got the same error message:

dynamiclinkmediaserver has encountered an error

[/DynamicLinkMediaServer8/releases/2014.03/shared/adobe/MediaCore/ASL/Foundation/Src/DirectoryRegistry.cpp-283] 

So then I tried the shell-script, everything ran as it should, but the error message (which has persisted for over 2 years) still remains.  Still can't use video or slideshows.

Ok - I finally figured this out myself.  I noticed when I started Lightroom fresh under a new user name, it created a folder in "Documents" named "Adobe" with subfolder "dymaniclinkmediaserver" and subfolder "7.0".  This folder was not present in my old user name "documents" file.  So, I copied the "Adobe" folder from the new installation, added it to my old installation "documents" folder, and whala - problem solved!  No error message and I am now watching video for the first time in Lightroom.  There are lots of others with this issue (I know from doing lots of googling on it) I hope this might help some of them.

I had replaced a couple of drives on my Windows machine with bigger ones and the letter of the drive containing my documents folder had changed. I changed it back to the original letter J:\ today and lo and behold my problem has gone too. So I guess Lightroom couldn't find that Documents/Adobe/dymaniclinkmediaserver/7.0 folder! All fixed now, cheers

Thanks Gregory. I'll see if there's anything our engineers can do to make sure that folder exists to avoid the generic warning.
