Hello Esther,

Looking through the manual it says you can File > Open or File > Import, doesn't seem to make a difference, both are ok to get to the Transposer dialogue box.

The file name for Transposer for C7 on the PC is Ca_ac007_Trnspsr2C7.exe, there hasn't been an update for it yet so it's the only C7 Transposer file version available - for PC.
