Scanner on Brother Multi-Function Not Showing in File, Select Source

[iowalaex]

This MFC printer is a Brother MFC-J870DW.
It is recognized as TWAIN and WIA by ABBYY FineReader and Foxit Phantom PDF, but not by IrfanView.
How to Add?

[declaration]

I have Brother DCP-9270CDN which is on my LAN. I have Windows 10 64-bit. I have installed full printer driver package made for windows 10 64-bit from Brother site. When i install irfanview 64-bit, it does not see any scanner at all, the twain list is empty. But when i install irfanview 32-bit, it sees both twain and wia scanners for that Brother printer.
Is this normal? What could be the problem?
Other 64-bit programs like paint or Corel Photopaint or Adobe Photoshop 2021 see this scanner no problem.
Why not Irfanview64?

Some drivers are not compatible with IrfanView 64 bit. Not sure why. Anyway, it might be little inconvenient, but both Irfanview 64 bit and 32 bit can be installed simultaneously and they are completely independent.
