VBS set CS6 export options with multiple Illustrator versions installed

Hi,

I have two versions of Illustrator installed on my machine (CS6 and CC).

I need to create an application that will save AI files as PSD. The problem that I have is that both CS6 and CC open when I try to set the Photoshop export options.

Below is the code I use:

Dim illApp = CreateObject("Illustrator.Application.CS6") 'Opens Illustrator CS6

Dim expPSD = CreateObject("Illustrator.ExportOptionsPhotoshop") 'This line causes Illustrator CC to open

My questions is, is there a way to set the export options for CS6 only?

Thanks in  advance for your help
