+
+   TopSpin requires 32-Bit libraries, which are not installed automatically
+   on 64-Bit OS since RHEL-6  / CentOS-6.
+
+The recommended way to install the required TopSpin runtime environment
+for CentOS-7.x86_64 is the Bruker-Addon Repository:
+
+  Installation of Bruker-Addon Repository
+
+     * yum --nogpgcheck install
+       ftp://ftp.bruker.de/pub/nmr/CentOS/7/Bruker-Addon/bruker-addon-latest.x86_64.rpm
+
+   Then you may install other required packages with yum (the bruker-repo is
+   not enabled per default,
+   you must add --enablerepo=bruker to the command line)
+
+   The next step is to enable the EPEL repository, if not already done:
+
+     * yum install epel-release
+
+   Now you can install the TopSpin environment:
+
+     * yum install --enablerepo=bruker   bruker-topspin-environ
+
+   or
+
+     * yum install --enablerepo=bruker   bruker-acquisition-environ
+
+   If you open a new shell window the alias yumb is available as shortcut for
+   'yum --enablerepo=bruker'

+                              Installation Caveats
+
+Default network assignment is not supported by the Flexlm Licence Manager
+
+   The default network interface names are something like 'eno1' / 'ens1' or
+   'enp0s3' , which are not detected by the flexlm library. 'lmhostid'
+   returns an empty string.
+
+   You may install the bruker-network-service which will create the required
+   eth0 as IP link on each reboot. The link is set to the default device
+   ens1.
+
+   If you use or want a other device, e.g. eno1, * either copy and edit the
+   config file /usr/lib/systemd/system/topspin-network.service and change
+   --device=ens1 to --device=eno1
+
+     * yum install --enablerepo=bruker  bruker-network-service
+
+     * cp /usr/lib/systemd/system/topspin-network.service
+       /etc/systemd/system/topspin-network.service
+
+     * Edit /etc/systemd/system/topspin-network.service
+
+     * systemctl enable topspin-network.service
+
+     * systemctl start topspin-network.service
+
+   * or reinstall FlexLM from the TopSpin DVD and specify eno1 when asked for
+   a network interface name for the License Manager.
