Unable to upload code using FTDI in 1.6.12

I’ve got a arduino mini with a FTDI usb converter.
On IDE 1.6.9 it works fine. I’ve just downloaded and installed 1.6.12 and am getting:

java.io.IOException: Cannot run program “REMOVE/bin/avrdude”: CreateProcess error=2, The system cannot find the file specified

An error occurred while uploading the sketch

Going back to 1.6.9 and it works again.
