GroupWise Disaster Recovery (Reload) not installing on SLES 12

Reload doesn't install on SLES 12 and reports the following error:
/var/tmp/rpm-tmp.XORr5n: line 26: ./install: No such file or directory
warning: %post(beginfinite-reload-5.0.000-1.i586) scriptlet failed, exit status 127"

This occurs when some libraries are not installed.

To resolve this issue go into YaST and install:
rpm-32bit

Then run the installer again.
