Can you try to save the output file to a different location? Something easy like "C:\" for example.

Sometimes this helps...

Jan Kinne The problem is that i dont have acess to location or change the location output file... I think it comes by default...

Can you access the location outside of the program (i.e. via your file explorer)?

You could also try to start the program as administrator (right-click the program and "run as administrator").

Hi Gino,

This sounds like a simple thing. I haven't used the DSAS software but I am assuming that, since it works under ArcMap, it might be the case that when you try to export something into an .XML file or other format, you are supposed to indicate first the workspace where it is going to be saved. If you enter a filename, ArcMap thinks that the file already exists and looks for it. You might also want to check if there are invalid characters in the output filename. Or perhaps contact the author(s) directly.

Good luck!

Thank you Jan Kinne and Federico Solano the error was very simple to solve. In the guide to program appears the solution.

"The computer must be configured to English (USA) and the date format must be mm/dd/yyyy. From the Control Panel menu, choose 'Regional Configuration and Language'> select 'English (USA)' and modify the date configuration to 'mm/dd/yyyy.'"...

Thanks for answering my question.

Hallo Gino Figueroa i still get the "Unable to find output file 'C:\Users\...DSASCore.out.xml" even after changing the region to USA and modify the date. I've tried to reinstall the ArcGis and DSAS too and still got that problem.

Any other solution? Thanks
