While installing Documentum Transformation Services you may encounter this cryptic error
LCMerror9001 – Turnkey service MySQL for Adobe LiveCycle does not exist.
If you searched the web you may find this document from Adobe which may not provide much help in fixing the problem.
Adobe Support Package for DTS 5.3 SP3 includes Adobe LiveCycle PDF Generator 7.0. It internally uses JBoss and MySQL. The above error can occur if there is a space in the path to the MySQL installtion. The service uses the the path to the binary, but the problem lies probably with the option it takes which is the path to my.ini.
Overall, the best approach is to avoid paths that include spaces.
