Running 32 bit apps on 64 bit debian

[Van Snyder <van.snyder@sbcglobal.net>]

I'm trying run 32 bit LinuxSusser on 64 bit Debian 12 bookworm.

When I try to run it, I get
./LinuxSusser: Command not found.

"ls -l ./LinuxSusser" respnds
-rwxr-xr-x 1 vsnyder vsnyder 12698092 Feb  8  2013  LinuxSusser*

"dpkg --print-architecture" responds amd64
"dpkg --print-foreign-architectures" responds i386

"file ./LinuxSusser" responds
./LinuxSusser:      ELF 32-bit LSB executable, Intel 80386, version 1
(SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for
GNU/Linux 2.6.0, stripped

but "ldd ./LinuxSusser" responds "not a dynamic executable"

I used to run it in Debian 10.

What am I doing wrong?
