That TIFF file uses 128x128 pixel tiles that are compressed with JPEG compression.

I was able to open it in Paint.NET after re-saving it in IrfanView with LZW compression.

The small increase in performance you get coding in C++ over C# is hardly enough to offset the headache of coding in the C++ language. ~BoltBait

am I right that at this case (lzw compression) - I will loss 4th band?
original have 4bands, re-saving + apply lzw at irfan - resulting tif have only 3bands - looks to me

That is correct.

IrfanView only reads the RGB image data, it ignores the 4th channel in the file.
