First close all other running applications.
Try choosing another directory on your hard disc for the output file. Make sure you have administrative permissions to save files to this directory.
If this does not help, try adding another file to the program. Choose the same parameters as before and try to convert the file. Do you get the same error?
In case these recommendations are not helpful, please attach a screenshot of the program showing the output file path.
Regards.
