32 bits de aplicação no linux de 64 bits não funciona

Question

Estou executando o Linux Mint LMDE versão de 64 bits, eu tenho que instalar este software i386 para usar o meu modem. Então eu fiz isso com o modo --force-architecture, instalação concluída com erros. Aqui está o log

dpkg: warning: overriding problem because --force enabled:

dpkg: error processing crossplatformui (--install):

 crossplatformui

Agora, se eu iniciar o aplicativo, ele diz

phanindra@phanindra:~$ ztemtapp 
/usr/bin/ztemtapp: 4: exec: /usr/local/bin/ztemtApp/bin/App: not found

Como consertar isso?

Atualização:

Eu instalei o ia32-libs agora

e agora diz

phanindra@phanindra:~$ ztemtapp 
/usr/local/bin/ztemtApp/bin/App: error while loading shared libraries: libQtGui.so.4: wrong ELF class: ELFCLASS64

quando eu iniciei o aplicativo
