ZTE K-3571-Z Vodaphone unlock

[alkunlocker]

This is my second unlock (the other also a different ZTE); a great service, thanks.
In the dc-unlocker2client, I get the standard message ("For correct ZTE modem detection, please plug modem with invalid operator SIM inserted. Wait till software starts the modem, close ZTE software and then you can detect modem with DC-Unlocker").
Unfortunately I had to remove the 'ZTE software' (Vodaphone) because it was overriding my Telstra mobile broadband connect software (on a different ZTE modem dongle) and I wasn't able to connect to the internet. I am running Parallels Desktop on a MacBook, and am online via Telstra, dc-unlocker client booted up, the K-3571-Z plugged in, can't make progress.
Please help

Sorry, do not understand where is the problem? You can not detect device by dc-unlocker?

That is correct.
Your software (dcunlocker client) says to insert the modem (ZTE K-3571-Z) with an invalid operator SIM inserted and wait until the ZTE software starts. Here is the issue; the ZTE software, which I assume to be Vodaphone internet connect software, had to be removed because it was overriding my other Telstra internet connect software (the only way I can connect to the internet here).
So I am unable to follow the instructions given in dc-unlocker software to detect the device.

Then close the software that you use for connecting to internet with this device (telstra software). Or install device on other computer ant try detecting there.
