An error popup with this message:

Unexpected error launching InterMapper application.
Please notify Dartware Technical Support.

is a general error, but the most frequent cause is a missing or inaccessible Java installation. Java is required for the InterMapper console or InterMapper RemoteAccess.

If this error is received, please give the following command at the command line:

java -version

If the response indicates a problem, install or uninstall/reinstall Java and then launch InterMapper or InterMapper RemoteAccess normally.
