I bought a Plustek OpticFilm 7600i last week. This scanner is shipped with an install DVD of Silverfast SE Plus to deal with Multi-exposure and iSRD.
I installed the software on a windows XP SP3 machine.
My software is registered with the purchased serial number.
Everything works fine. I can use Multi exposure and iSRD but I can't select 48 bit color and 16bit Grayscale in scan types.
I have a SE PLus version so it was supposed to work with 48bit color.
Here is the screen shot of my silverfast SE Plus:

Can you please help me ?
Maybe the serial number is wrong
I downloaded a demo version of Silverfast Ai. I can choose 48Bit color.
