Following issues with installation of DMC 3.1.

1. silent install is not supported in a way as it was with DSM. One can not enter the information for the repository database in a setup file. The -silent option is not suported?
2. The crypt.sh gives an error:
   # /opt/ibm-datamgmtconsole/dsutil/bin/crypt.sh password
Exception in thread "main" java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version; class=com/ibm/aps/tools/util/crypt/CryptUtils, offset=6

Thanks Tiemen for your feedback! Silent install is not supported yet in DMC v3.1. We will evaluate whether it can be added into the following up update. 
For the crypt.sh error, I will create an internal issue to track and post update here.
