I started by deleting all the JTX tables and feature classes out of my development environment and copied our production JTX content in its place. I was sure to assign privileges to the copied content and register as versioned. I then ran the post install (which found the existing system table repository) and I selected "Minimum configuration". Unfortunately, the post install failed! Last part of the log is below:
