Visual Paradigm for UML 7.2 on Ubuntu 64Bit

Hy

I need to install Visual Paradigm for UML 7.2 on Ubuntu 12.04 64 Bit.
When i install the 32-Bit Version, i get this error:

An error occurred:
java.lang.UnsatisfiedLinkError: /home/…/Desktop/VP_Suite_Linux_4_2_sp2_20100806.sh.15189.dir/jre/lib/i386/xawt/libmawt.so: libXtst.so.6: cannot open shared object file: No such file or directory

I’ve read in the forum that i have to install the 64-Bit version, but on cs.visual-paradigm.com there is only a 32-Bit version.

Thanks for your help
