You are partially correct.

The exclamation mark is because there is a conflict with the driver and the
chip in the programming cable.

Most inexpensive programming cables have an unauthorized copy of Prolific's
USB-to-Serial chip in them. These copied chips use the same Prolific driver
that the genuine Prolific chips require. Prolific eventually changed their
drivers after v3.3.2.105 to not function (hence the error) with the
unauthorized copies.

Windows Vista and newer (ie: 7, 8 & 8.1), will automatically install the
latest driver when a USB cable with a Prolific type chip is plugged into a
USB port that doesn't already have a driver configured. If the cable has an
unauthorized chip, the driver installation is guaranteed to fail.

The only fix that will eliminate the conflict with an unauthorized Prolific
chip is to downgrade the driver to at least v3.3.2.105. Some of the Chinese
programming software have a conflict with the v3.3.2.102 or v3.3.2.105
Prolific driver versions (CHIRP has no such issues and runs fine) so the
general recommendation is to downgrade to the v3.2.0.0 driver.

Windows XP does not automatically install the latest driver, but is
recommended that v2.0.2.1 is the driver version to install to avoid a
conflict with an unauthorized copy of the Prolific chip.

Other solutions would be to purchase and use a programming cable with
genuine Prolific chip or a programming cable with another brand of chip
(FTDI for example).
