Liquid rescale - one of the first 'extras' installed in my linux flatpak.
The windows version is 32 bit and comes as an installer. Hate those installers. This one in particular does not want to install if Gimp 2.8 is not there.
Possible solutions,
Steal the files from a previous installation.
Use a utility such as uniextractor to unpack the installer.
You do need a Windows Gimp 2.10 that supports 32 bit and the latest (fixed) Gimp package
gimp-2.10.0-setup-2.exe works.
As well as the lqr files, a 32 bit
intl.dll is needed. I took one from a 32 bit gimp 2.8 installation.
All-in-all, these files go in your Gimp 2.10 profile
C:\Users\your-name\AppData\Roaming\GIMP\2.10\plug-insgimp-lqr-plugin.exe liblqr-1-0.dll plug_in_lqr_iter.exe intl.dll and if needed batch-gimp-lqr.scm goes in scripts.
