connect jour jtag adapter to the CPLD.
Start impact on your PC.
Initialize the JTAG-Chain.
Choose the Readback operation for the connected device.
Save the Jedec file.
That's how it works...unless...the Readback protection bit is set.
In that case, forget it.
Have a nice synthesis

The error message you are getting indicate the software is not installed correctly - not necessarily that the device has read protection enabled.
If read protection is enabled, no, you cannot readback the Jedec file so you cannot clone it.
