Our installation of Enforce repeatedly failed, after some analysis we found that on locked down machine where JRE directory has only read access Enforce would not install.
This had error: Process wrote to standard output: Error occurred during initialization of VM
After we changed file permissions the Enforce server installed.
Release : 15.8 MP3
Unknown at this time, a low priority ticket has been filed with engineering.
Temporarily change the permissions on the JRE installation directory so that Enforce installation can complete.
