I’ve reverted to Lightroom being my main processor but am very happy to use Photolab to preprocess certain files before continuing to process them in Lightroom Classic.
It began as an intermittent problem but now it seems to be almost continuous. I can send files from LR to PL but more often than not cannot return them to LR. I can watch the green progress bar creeping from left to right but in most cases it gets so far, gives up and goes red. The export fails. Sometimes it does get through successfully and the image looks great, and now and again, the image gets through
but there is a rectangular network of coloured horizontal lines superimposed over part of the image. I have reported this to DXO tech support and they have asked for various files, including sidecar files, but they seem to have given up.
Interestingly I downloaded a trial copy of PureRaw and tried that, and this fails as well! In every case I’ve tried I get a more or less black image with a pattern of tiny coloured red/yellow/blue dots on.
Once again tech support seem to have lost interest. This is certainly way beyond my capabilities to solve.
Unfortunately it doesn’t work. I successfully did the LR>DXO>LR process a few times and it did work. Then I tried using PureRaw which failed to export back to LR, and then the Photolab>LR export failed as well.
I have gone back into Folder properties as you suggested, unticked “read-only” and closed it but it is impossible to keep that box unticked. It just automatically ticks itself again.
I have found the following article via google with some suggestions.
However I’m a bit of an IT-phobe so am reluctant to follow the detailed procedure too far in case I do some thing critical but wrong!
I am grateful for your suggestion but how did you have to go before you got a solution?
