Thread: OCR in Irfanview

  1. #1

    Default OCR in Irfanview

    Does the KADMOS OCR work in 64bit Win 10? I just updated and installed the plugin. I get:

    Can't load PlugIn: "OCR_KADMOS.DLL" !
    Please install or update PlugIns from IrfanView homepage
    enable the PlugIn in 'Help->PlugIns' menu.

    I'm guessing it's 32 bit.

    From the FAQ on

    64-bit will be faster for some operations due to supporting more RAM.

    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)
    • Some old 32-bit PlugIns (like RIOT and Adobe 8BF PlugIn) work only in compatibility mode in IrfanView-64
    • Command line options for scanning (/scan etc.) work only in 32-bit (because no 64-bit TWAIN drivers)
