OK I got the same error on Win7 Pro, mmmm

1) disconnecting the USB programmer, shut-down vm, closing Parallels Desktop (just in case)
2) restarting everything ... (Parallels, Windows, ClonixConfig v4.1)
3) connecting the USB programmer, selecting NoV-64, plain config, proceed, same problem ...
4) changing USB cable, nop, still not working
5) deleting driver, reinstalling driver, Yes! it's working now 8-)

Now, I must show you the steps on how to REALLY delete a windows driver from the system, follow me ...

1) close the PIC programmer and the ClonixConfig applications

2) We must configure the Device Manager hidden driver viewer option

a) Control Panel -> System -> Advanced System Settings
b) System Properties dialog: -> tab: Advanced -> button: Environment variables
c) Environment Variables dialog: box: System Variables -> button: New ...
d) New System Variable dialog:
Variable name: DEVMGR_SHOW_NONPRESENT_DEVICES
Variable value: 1
press OK (close New System Variable dialog)
press OK (close Environment variables dialog)
press OK (close System Properties dialog)

3) Starting Device Manager and activating the hidden driver viewer option

a) Control Panel -> Device Manager
b) menu -> View -> Show Hidden Devices
(this works only because we have set the environment variable in the previous step)
c) explode the Port(COM & LPT) section
-> you should see several grayed devices (driver for unconnected devices)
-> you should see one or several "Prolific USB-to-Serial Comm Port" entries.
d) we must remove all "Prolific USB-to-Serial Comm Port" entries except one
-> for each entry except the last one
-> select a "Prolific USB-to-Serial Comm Port" line
-> right mouse button, then select Uninstall,
-> show the "Confirm Device Uninstall" dialog, uncheck the "Delete the driver ..." option and the press OK
e) we must remove the last "Prolific USB-to-Serial Comm Port" entry and the physical driver from the system
-> for last entry
-> select a "Prolific USB-to-Serial Comm Port" line
-> right mouse button, then select Uninstall,
-> show the "Confirm Device Uninstall" dialog, CHECK the "Delete the driver ..." option and the press OK
-> at this point we have remove all trace of the original driver
f) menu -> action -> Scan for hardware changes
-> this will force windows to rediscover the Prolific device, download the latests driver and install it
g) explode the Port(COM & LPT) section
-> you should see the "Prolific USB-to-Serial Comm Port (COMx)"

4) restart ClonixConfig and follow the normal procedure and it should work as before ...
