If you use HACloud, note the installation requirements, based on your environment.
On Windows. If you temporarily set the TMP or TEMP environment variables as described above (Setting a TEMP directory for install4j), a chained installation of HACloud and MSS needs no other adjustments.
On Linux/UNIX. You cannot run a chained installation.
Run the INSTALL4J_TEMP var set and the -J-Djava.io.tmpdir switch separately, each with administrative permissions.
If you plan to install MSS and HACloud separately, install MSS first.
