If you have successfully installed Workflow, FormServer or FormManager and then run LiveCycle Configuration Manager (LCM), you may receive the following error:
Configuration Manager Errors Error Code:LCMerror101 Message: Livecycle modules could not be copied to working directory.
This is due to the version of the JDK being used: JDK 1.4.2_10. This JDK version has broken backwards compatibility, and so is not supported for LC7.
Use a different JDK version and this will resolve the problem.
