How to use Canon LiDE 400 Scanner driver within Corel Photopaint 2020?

Hello all. I bought a new laptop with Win10 Prof and attachted a new Canon scanner, CanoScan LiDE 400, to that. Installing the current Canon scanner driver for that.

Unfortunately, the scanner appeared within Photophaint (latest version = 2020) only as a VIA scanner driver with absolutely poor scanning possibilites.
Why is there not a TWAIN scanner driver?
Only the Canon scanning software appeared with "ScanGear", which is the desired driver for within Corel Photopaint.

I read in the web, Corel Photopaint 2020 is a 64-bit app, and the Canon driver a 32-bit app.
Unbelievable, that Canon does not have a 64-bit driver.

Has anyone an idea how to use the LiDE 400 within Corel Photopaint directly?

Thx, Michael.
