Passolo Demo 2018: Error: Cannot Write Targer File

Hello.

I have problems Generating the Target File using Passolo Demo Version 2018.

i guess i did all that i could to solve this issue without success; i created a new path rule, changed the string List Settings, and even reinstall the Demo Version of Passolo.   but this message always pop-up:  Error: Cannot Write Target File. 

could you help me to find a solution to my problem?  

I'm currently working with an Ing file, but i encountered the same problem working with different types of files (i'm newbie using this tool).

Thank you
