[harry12345]

When starting zdclient I get the following errors:
/usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so: falsche ELF-Klasse: ELFCLASS64

I am running Ubuntu 11.04 and zimbra desktop 7.1.2.
ia32-libs is installed.

Please help.

Thanks

Why don't you install the missing libraries?

[harry12345]

missing libraries were installed:
-rw-r--r-- 1 root root 23048 2011-04-20 22:20 /usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so.
but I can't fix the first error:
/usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so: wrong ELF-classe: ELFCLASS64

Thanks for help,
harry

Is a 64-bit ZD-Version available?
