Unfortunately I had to reinstall GIMP today and now I want the LQR plugin back but it doesn't work… When running the installation file I got this warning message:
GIMP installation was not found. You must install GIMP before running this installer. If you have GIMP installed, you may proceed, but you need to specify the GIMP installation folder manually.
I choose C:\Programs\GIMP 2\ (I couldn't choose subfolders anyway). When starting GIMP again it says the procedure entry "gimp_drawable_get_thumbnail“ wasn't found in DLL „libgimpui-2.0-0.dll“. GIMP starts (and works fine) but LQR doesn't show up in the layer menu.
Any ideas what went wrong? Thanks for your help! I'm using GIMP 2.8.18 and Win XP.
