"Invalid Image File"

(moved from inappropriate thread)

I installed the LightZone-Installer-4.1.0beta6-x86.exe on my Windows 7 Pro 64bit machine.  I'm receiving the following error when I trying and edit a NEF from a Nikon D7100.  (But I get the same error when I try to open a jpg, so maybe I installed the wrong version.)  The error says "Invalid Image File   C:\Users\Bill\AppData\Local\Temp\LZRAWTMP1702806442484561010.ppm".   Message here: http://www.intergate.com/~wcb/lz-error.jpg

Perhaps I downloaded and installed the wrong beta -should I have installed the LightZone-Installer-4.1.0beta6-amd64.exe beta? Also, I installed it alongside LZ 4.0 rather than "over" the old version.


As I understand it the amd64

As I understand it the amd64 version is for 64bit Windows devices.


In theory the 32bit x86 version should work (or at least that position that MicroSoft take about their own software) but there may be some challenges.


Not sure why you would see that particular error or a Temp RAW file but in any case try the amd64 version and enjoy the additional performance it seems to offer.


If that fails then there is something else going on.







Thanks, Grant - I'll give it a try

And there was much rejoicihg

I installed the amd64 version (over the previously LZ installation - I wonder if that was the cause of the "invalid image file") and the error went away.  Additionally, the update to dcraw 9.2 works very well on the Nikon D7100 NEF - which is great news!  The image is a little brighter than I would like, but the colors are correct, so I'm pretty stoked about that.

Thanks, All.

Do you have a raw tone curve?
