Hi Pierre )
Why XnConvert 32 bit new versions not work on Windows XP ? Why limited only 1.65 version ?
As I understand , in new versions there is nothing revolutionary and can do full compatibility.

Newest version of QT use new API functions

But what for this functions in converter?
After all goal such converter only convert images and all.
Also in new 32 bit version have HEIC/HEIF , but if I do convert from any format to HEIF , process aborted with error.
Also in any 64 bit version not support old 32 bit plugins e.g LuraWave JPEG2000 , this format very good in compress images and can compete with HEIF / HEIC of compression rate.

Between XP and 2000, many functions of Windows API have changed.

HEIF is only supported on x64bits

Sorry right, it's not HEIF library (64bits only) packaged in XnView but the HEIF codec from Windows Store

And wheen be fixes ?

which fix?

[Xn User]

1) in XnConvert not added Lanczos2
2) in XnViewMP 32 bit have read and write HEIC which can not use if select as save or write , or read
HEIC also applies and XnConvert 32 bit

XnView/XnConvert 64bits has a HEIC plugin, XnView/XnConvert 32bits use the MS codec, and has problem...
