it seems the plugins for the new 4.40 were withdrawn; the links are empty and I can only find the 4.38 plugins
So, what does the 64bit release bring to the table?
Advantages of IrfanView 64-bit over 32-bit version:
• It can load VERY large files/images (image RAM size over 1.3 GB, for special users)
• Faster for very large images (25+ Megapixels, loading or image operations)
• Runs only on a 64-bit Windows (Vista, Win7, Win8, Win10)
Advantages of IrfanView 32-bit over 64-bit version:
• Runs on a 32-bit and 64-bit Windows
• Loads all files/images for normal needs (max. RAM size is about 1.3 GB)
• Needs less disc space
• All PlugIns will work: not all PlugIns are ported (yet) to 64-bit (like OCR) and some 32-bit PlugIns must be still used in the 64-bit version, some with limitations (see the "Plugins32" folder)
• The Unicode and many Adobe 8BF PlugIns can't work on 64-bit
• The TWAIN drivers with 64-bit support are rare
