Lightroom 5.3 (Perpetual) won't import my photos

I also had this issue with LR 6.3 / CC hanging or not importing all of my NEF photos -- either from my camera or from the HD.  As mentioned by other posters, the fix is to remove any movie files from the directory being imported.

I'm having the exact same problem. The program just hangs.

Yesterday I upgraded my OS from Win 7 Professional to Windows 10.  Today, when I tried to import raw photos from today's shoot, I got the subject response.  I tried several things, but then realized that the error message was pointing to the target, not the SD card.  When I looked into the Destination Folders on the right, it was pointing to C:\Users, not C:\Users\John\Pictures.  Once I changed the destination, it worked OK.  I do not know if it will remember my choice, but worked this time.

Same here.  Lightroom CC on my Macbook Pro.  Although it may have been a coincidence, all was well until I installed the Lightroom app on my Android and iPad in order to sync photos. Regardless, in attempting to import from a card or from the desktop, 1.) an entirely new screen unlike the standard Lightroom window pops up with options to "Add photos from a source," as shown below 2.) no option is given as to where (which folder) to import these photos to in Lightroom, 3.) some or none of the files will "Copy and Import" randomly to a random, unselected folder, 4.) importing will get hung up indefinitely, and 5.) "An internal error has occurred. assertion failed!" may or may not appear, as shown below.  I have uninstalled the apps on my phone and iPad as well as rebooted numerous times without any successful outcome.  Any revelations out there???  Frustrating!!!

What's worked for me thus far has been to drag and drop files from the origin folder directly into LR.

I ran into this same issue last night.

I was able to resolve it by restarting my computer.

Here's how I was able to create the issue.

I was previously using Lightroom 5.7 on OSX 10.10.5

I had recently upgraded to Lightroom CC.

I launched Lightroom from my dock expecting CC, but 5.7 launched, so I launched CC - I'm guessing it was the first time I had launched Lightroom CC.

I closed down 5.7 and started to work in CC, but ran into the import issue when I tried to import from an external Lacie drive via Thunderbolt.

I closed down CC, then restarted my computer.

This time I launched Lightroom CC without touching 5.7

It worked for me, hopefully someone else will find this useful.

It would appear the Adobe and Microsoft are trying to see which can embed the stupidest errors in its software.

If there are any movies present in the folder from which images are to be imported no images are shown in grid view even though the individual images may be viewed in the import window. The actual import process won't even start. To solve this problem simply move the movies elsewhere so they are not part of the import and the process will proceed normally.

I am also having the problem.  Lightroom 5.3 on Mac running Mavericks.  Can't sync folder, can't import.  Lightroom appears to be importing or syncing, but hangs at end.  Even when just adding to lightroom - not moving or anything.  Have to quite the import and restart to get the option.  THIS HAS BEEN GOING ON SINCE I PURCHASED LIGHTROOM 5 from Creative Cloud almost a year ago, I've asked for help in forums off an on for months...yet Adobe has not addressed my problem.  Time to make some phone calls....

I have the same problem importing in to Lightroom 5.3. Get the message images were not imported because they could not be read. It shows the previews and then looks like it is importing but gets stuck forever in the import screen, no images show up there. It happened in early January for no reason I can figure out just out of the blue, worked fine in December! I have Mac 27 " desktop running OS x 10.7.5. I have tried deleting preference file. The only way I can import is to get the images in to a folder through another avenue. I used Adobe DNG converter, put files on an external hardrive, then imported without moving just added to catalog, this works but is a real pain. I am using Canon 5D and a Promaster card reader.  I also have a Mac Book Pro running 10.8.5 with Lightoom 5.3 and do NOT have this problem using same card reader, same CF Card and same images!

Any helpful remedies would be appreciated!

Hi, I just started having this issue also using Lightroom 5.3 with Windows 7. Have tried different cards and a different card reader. I use the Copy selection, in fact that is the only available option when using a card on my screen. My prompt states that Lightroom has stopped working and that Windows will try to find a solution, later a new box states that Windows will close the program and notify if a solution is available. Have to hit the close button because Windows never is able to close the program itself.

If I download from the card reader with Adobe Bridge and add to the hard drive and then import with Lightroom it worked but that is not an ideal work flow for me. Looking back at the dates of imports it looks like it began 1/10/14 or 1/12/14 on my set up.  I don't know how to check the permissions as Geoff suggests. Glad to know others are having similar problems so will use the work around until a solution is suggested.

Thanks!
