If it doesn't work, I think it's a UXS problem :S

Can you copy past your modification ?

normally, the standard thing is :
<Compression>
<use>yes</use>
<soft>pngquant.exe</soft>
<parameter>--force --verbose --ordered --speed=1 --quality=30-90 --ext .png</parameter>
</Compression>

So, UXS transform that in :
xxxPathtoUXSxxx\Ressources\pngquant.exe --force --verbose --ordered --speed=1 --quality=30-90 --ext .png xxxfiletocompressxxx

If you take a look at the logx.txt in the log folder, you must see a line like :
[12:05:44] - > PNGQuant command: "C:\Developpement\Github\BIN\Ressources\pngquant.exe" --force --verbose --ordered --speed=1 --quality=30-90 --ext .png "C:\Developpement\Github\BIN\TEMP\MIX3\MIX\screenTEMP.png"
[12:05:45] - PNG Optimization (PNGQuant): C:\Developpement\Github\BIN\TEMP\MIX3\MIX\screenTEMP.png(416 KB -> 110 KB)

(I just did it to have an exemple ^^)
