Error after installing gmic in Gimp 2.8

[Zero01]

GIMP 2.8.22
G'mic_gimp2.8_qt_win32
Installed on a Windows Vista 32-bit OS in VirtualBox VM on Windows 10 64-bit host.

I get the error message after clicking on "G'MIC-Qt.." in the Filters menu

Code:

"This application failed to start because it could not find or load the Qt
platform plugin "windows"
in". Reinstalling the application may fix this problem

after clicking OK another message appears, reads:

Code:

This application has requested the Runtime to terminate it in an
unusual way.
Please contact the application's support team for more information.

and then I get:

Code:

GIMP Message 

Plug-in crashed: "gmic_gimp_gt.exe"
(C:\Users\mart\.gimp-2.8\plug-ins\gmic_gimp_qt
\gmic_gimp_qt.exe)

The dying plug-in may have messed up GIMP's internal 
state. You may want to save your images and restart GIMP to
be on the safe side.

I tried re-installing but that didn't help. Also, my plug-ins and scripts come from my 64-bit system, so not sure if anything might be clashing...
EDIT: Got rid of all the .exe files from ' .gimp-2.8\plug-ins ', except for the plug-ins for Gap, not sure if .py files are specific to any particular 32- or 64-bit OS...
Just noticed there is no 'Python-Fu' under 'Filters, so no Console either...

Any help greatly appreciated.
