What steps are you trying? Please be exact, state the exact steps you are using in Lightroom, using the exact Lightroom names of the steps.
What happens when you try?
What is the error message? Please quote the error message word-for-word, verbatim.
well, I'm using the swedish language version but will try to translate.
1. Import - left section of LR (choosing catalog with RW2 files)
2. Getting msg in view part of LR "no preview available for this file"
3. When clicking on IMPORT (right section) getting msg "file not supported och damaged"
Works without problem on my old PC on LR 5.4.
My first guess is that you haven't really installed Lightroom 5.7.1, you have actually installed some earlier version of Lightroom. ("not supported or damaged" usually indicates your version of Lightroom is too old to read from your camera)
So please double-check the actual version of Lightroom that you are using and please report the results.
I sure have 5.7.1 installed.
JPG-files works fine but RW2 no.
I've also reinstalled in once to be sure i didn't miss anything the first time
My next thought is that some hardware is malfunctioning, maybe card reader or USB cable or USB port?
No, nothing wrong with the hardware. The RW2 files are on my harddisk already and I use the photos in other photo editing software (e g. PhotofunStudio).
It is only in Lightroom 5.7.1 I have the problem. Very strange.
Are these the .RW2 files straight out of the camera, no modifications at all; or .RW2 files as modified by some other software?
How did you move/copy the .RW2 files from camera card to hard disk? What were the exact steps you used?
Being a non-user of Panasonic cameras, I point out (and this may be totally wrong) that the Lightroom documentation at Camera Raw plug-in | Supported cameras indicates that Lightroom can read the .RAW files from a GX7, and .RW2 files from other Panasonic cameras. Does that mean anything to you, or am I totally off-base?
Yes, straight from the cameras memory card with file copy from the PC card reader.
I have also read the Ligthroom doc regarding .RAW from GX7 but don't understand, GX7 only produces RW2 files!?
And I have been working with RW2 files in Lightroom 5.4 for over a year now without any problem.
If you are getting error messages that say Lightroom cannot preview the files, and that the photo is either not supported or damaged, then I claim you have not yet ruled out the hardware transfer as a possible cause of the problem. In many cases, the RAW photo is damaged or corrupted while the JPG preview inside the file remains intact, and thus other software such as PhotofunStudio shows you the JPG preview not the RAW (I don't know, I never used PhotofunStudio). So, in my mind, there are good reasons why you want to troubleshoot your card reader/USB cable/USB port and also check your hard drive for possible problems.
PhotofunStudio is the software that comes with the purchase of the Lumix camera so it should be the "expert" on RW2.
I will see if I can find anything on the hardware side as you suggested.
Thank's a lot for your commitment.
I cannot believe that there are not 100's of frustrated Lumix G7 users with this issue.
Using Lighroom 5.7.1 - exactly as described - cannot display RW2 files
HOWEVER, downoad Photoshop from the same Cloud suite ... no problem what so ever.
Come on Adobe - what's the answer ? Better still, if it is an issue, can we have a lead time for native support of RAW Lumix G7.
The thread OP is talking about the GX7 which was supported in Lr 5.2. The G7 need Lr 6.1 and will never be natively supported in 5.71.
LR 5.7.1 is from Dec 2014. You need a version of LR newer than when a camera was first released for sale in a country that Adobe tests cameras in, usually the US, I think.
