DPP4 Convert and Save "Duplicate File Names" Error Message

[Lorinai11]

convert and save Digital Photo Professional 4 - version 4.2.30.0

I have been converting and saving files on in above software for years until yesterday.
I'm suddenly receiving an error message: Under these settings, files will be saved with duplicate file names. Check the file savings settings.
When I press ok, it just goes back to the 'convert and save' window. I tried it with and without clicking on Embedded ICC profile - no change.
How can I fix this?
Thanks
Claudia

Greetings,

This error usually means you're trying to save the converted files into the same destination as your source.  

You may also want to consider updating your version of DPP 4. The current version as of this writing is 4.17.10.
