TWAIN for Catalina don't work

[TWAIN for Catalina]

I used TWAIN.framework to scan the surface in my project.
The Catalina 10.15 beta version works fine, but after upgrading to the Catalina 10.15 GM version, it doesn’t work. Has anyone encountered this problem?

hey, I have the same problem.

I use Catalina 10.15 (latest version). and I can’t scan any documents (with Readiris 1è PRO°- due to the TWAIN who’s not configured for the latest versions of Catalina on Mac book

Our app works fine in Mojave, but it doesn’t work in Catalina. The TWAIN Driver does not work properly in Catalina.

So I haven’t tried this yet, myself. But the evidence suggests that Catalina has completely obsoleted 32-bit support. Any TWAIN application or TWAIN driver that requires any kind of 32-bit binary is going to fail. TWAIN applications and TWAIN drivers that support 64-bit should be okay.

64bit TWAIN Driver & Application can’t work well in Catalina yet.

Is that TWAIN driver using the Apple DSM under /System/Library or the open source TWAIN Working Group DSM under /Library?
