I am just learning ArcGIS 10.2 and it was working well until I tried to use the Export to a Geodatabase (single) option for a dbs table I made. Since then, it seems I now get the same Script Error for import/export functions. However, I just tried to export to Geodatabase (multiple) and error did not pop up. I spoke with tech support and they could not help me so far. I really do not know much about GIS so it is hard for me to fix this problem and cannot proceed with some things.
I just solved this problem. What you need to do is the following: In Windows go to: Control Panel -> Programs -> Uninstall a program.
Then right click on "ArcGIS for Desktop" -> Select "Uninstall/change".
The ArcGIS Setup dialog will pop up. Chose the "Repair" option.
After finishing the Repair procedures the ArcGIS will be working properly!
I resolved this error by repairing the data interop. installation. I also have background processing turned off.
