How can I instal eMClient to non system disk?

I need instal eMClient to disk D: (non system) but on instal  is not choice to instal to D: Program automaticaly instal to C: (system). Is there any way to instal to D.?

The install does not offer alternative locations, but as long as your drive is NTFS, you can use junction points. It works, but don’t know if eM Client company will support this method.
