Some weeks ago, Lightroom 5 started to show an error message every time I export a photo (from jpeg or DNG to any format, single image or batch, no difference).

Lightroom Error Message

(From German: "Attention, Export not possible: an internal error has occured")

The exported pictures are all there and fine, nothing is missing there. But the same error keeps coming up every time, no matter what settings I change in the export dialog.

Did anybody maybe have a similar issue?

  • \$\begingroup\$ do you have a custom action defined at the bottom of your export dialog? \$\endgroup\$

  • \$\begingroup\$ What version of Windows are you running? that error looks there is an issue with lightroom communicating with the OS to create the exported file. <win key>+R, type cmd, then type ver, and <enter> \$\endgroup\$

  • \$\begingroup\$ Disable plugins and try again. The dialog says it is failing to execute a program outside of Lightroom which can only be a plugin AFAIK. \$\endgroup\$

With the help of the comments I was able to solve the problem:

For some reason in the export dialog the "custom action" field was completely blank, instead of showing "no action". Changing this made the error message dissappear!
