I've got a tricky problem. Using LR3 and Vista, if I try to import any videos into catalogue I get a Windows dialogue box saying "video_thumbnailer.exe has stopped working" (and you cannot see the thumbnail for the videos, just the movie camera icon)

I also get a balloon message saying that Data Execution Prevention (DEP) has prevented video thumbnailer from working. Going to the DEP settings, when I try to turn DEP off for the video thumbnailer (which is located in C:\Program Files\Adobe Photoshop Lightroom 3.5) I get another dialogue box saying "This program must run with DEP enabled. You cannot turn off DEP for this program.

I have tried changing the DEP settings to work for essential Windows programs and services only, but to no avail.

I could live with the problem if if it happened only once per import, but the initial "video_thumbnailer.exe has stopped working" dialogue box reoccurs for every video files that it tries to import into the catalogue. I have just had to click the "close the program" button fifty times as I imported fifty videos with my photos.

Any thoughts of how to get around this? I would be happy for LR to ignore videos altogether, if that is possible.



p.s. if it means anything to you, the following is the problem signature:

Okay, I know it is not good form to answer your own questions, but after playing around for a while I have come up with half a solution:

By slightly renaming the video_thumbnailer.exe (I added "_old" to the end of the name) file the video thumbnailer cannot start, and therefore cannot stop working so I no longer get the multitude of error dialogue boxes.

It does mean that I do not see a picture thumbnail in Lightroom for the videos, just a message where the thumbnail should be saying the image cannot be displayed, but I can live with this as I really only use LR for photos and don't do a lot of videos.

It doesn't explain why the video thumbnailer didn't work, and it would not be a good solution if I wanted to organise videos in LR, so I would still be interested if anyone can come up with a proper fix.

Hi Ivor,

I'm glad you posted a partial solution.......it may help someone else down the road. I'm wondering if you have tried the LR4 beta? It has enhanced video support so perhaps the problem with the video thumbnailer got sorted out.

Mac OS 10.9
Lightroom 5

Canon 5DmII, EF 24-105mm f/4L USM, EF 135mm f/2.0L USM, EF 50mm f/1.4 USM

Thanks Julie,

I had tried it but it made no difference. I also decided that there wasn't enough there to warrant me spending lots of money that would be better spent on feeding my family!

LR4 Beta also mucked up my autoplay function so when I plugged in my memory cards the Import Using Lightroom 3 function did not work. Although I could see the option to use LR3, it would not work. I could only import using LR4 Beta. When I uninstalled LR4B, it still would not work until I installed the 3.6 update.

I use Vista, which is prone to problems like this. I might upgrade to Win7, or 8 when it comes out, to see if some of these issues disappear.
