With version 5.4.1 of NetWorx, after exporting a data file and trying to open it in Excel, I get an error message "... cannot be accessed. The file may be corrupted, located on a server that is not responding, or read-only."
This error didn't occur with previous versions of NetWorx.
If I exit out of the NetWorx program, then I am able to open the export data file in Excel without any error messages.
