I will use this blog post as an ArcGIS notebook. So it will be record of what Iearn but also how I solved the problems I encountered. I'm using Arcmap 10.3 on a Mac via the VirtualBox.
1) ArcMap export doesnt show save button and file name filed.
- Close ArcMap and go to the Start menu.
- Type in regedit in the box to bring up Registry Editor
- Back up your registry first.
- Go to HKEY_CURRENT_USER\Software\ESRI\Desktop10.0\Export
- Expand ExportDlg folder, in right panel, double click on "ShowOptionsPanel"
- Enter "1" for Value Data and OK.
- Close Registry and restart ArcMap. Test Export feature which should now show options.
