Looks like CPUSE build 2113 has a minor packaging issue:
LabSC> installer agent install /home/admin/DeploymentAgent_000002113_1.tgz
INFO Installing Deployment Agent package - /home/admin/DeploymentAgent_000002113_1.tgz ...

Specifically, it looks like it's a TGZ which is then gzipped again. The hash on the download page is correct for the version of the package which can be installed. The package as downloaded to my machine instead has this hash:
~/Downloads> md5 DeploymentAgent_000002113_1.tgz
MD5 (DeploymentAgent_000002113_1.tgz) = d9856795377944b9f21759e07f98b086
