When stopping or cancelling an initial IBM Installation Manager install, you receive an "Installation data" error message.
This occurs when the install is cancelled and terminated without allowing the application script to fully exit the program:
Error restoring Installation Manager state
Installation data has incompatible version 0.0.4; expected Ý0.0.2,0.0.3
This error occurs in IM version 1.3.2 or lower.
Resolving the problem
Upgrading to version 1.4.1 or the latest release of IBM Installation Manager prevents this error. Also, if you must terminate the application before the install completes, allow the install script to finish running. That way, it can remove the files that initially copied to the computer.
