You can save and send files in eDrawings 64-bit installations.
When you use Save As or Send As to create .exe or .zip files from eDrawings x64, a message in the dialog box notifies you that the file will run on 64-bit systems only.
If you use Save As or Send As and you also have the eDrawings 32-bit version installed, you can set Save as type to eDrawings 32-bit Executable Files (*.exe) or eDrawings 32-bit Zip Files (*.zip).
If you use Send As and you also have the eDrawings 32-bit version installed, the Send As dialog box contains options to send 32-bit .exe and .zip files.
