The text formatting in that error message is very bad. This means you either have some bad characters in the volume and path names, or you blocked out some text for privacy issues.
The folder name included location and event details which are not relevant to my post.
Do you have any ideas about this issue? I'm having a hard time finding answers anywhere on this.
It works on WIndows 7 with CC 2015.8. What OS version are you using?
Working fine here on a Win 7 Pro system.
Check the folder destination where the resulting TIFF file will be saved (In the External Editing tab of the preferences and also look at the Export dialog window) for the proper permissions.
Also check the format and permissions of the drive the image is stored on.
Thanks for the replies.
I am using Mac OS Sierra 10.12.2. It is a brand new 2016 Macbook Pro. I recently migrated my data, programs, etc and have not used Nik Efex software/plugins since moving to the new machine (I have uninstalled and reinstalled the Nik software but the issue remains).
I am looking at the External Editing tab but don't see where it specifies that the TIFF file will be saved. Here is a screen shot of it, in case it helps (showing Color Efex but I have the same issue with other Nik Collection programs):
I checked the export dialog. Files export to my internal hard drive and that works fine.
I checked the permissions for the external drive where the file is located, and it says read and write for all three levels:
I hope this helps narrow down what the issue is! Thanks for your continued assistance folks!
Add your username to the list and give it Read & Write permissions.
By default the Everyone group is limited even with Read & Write permissions.
Thanks Just Shoot Me. I made the change as you recommended. (I'll try to do this for all my many external drives!)
Do I need to reboot, or restart the Adobe software or anything? I tried to Edit In > Nik SIlver Efex after making the change and I still get the error message that Lightroom was ..."unable to prepare the file... It will not be opened".
Does that file open in PS? Edit In > PS.
Yes, fortunately selecting Edit > PS does work. Opens it in PS CC 2017.
