By default MagicDraw configuration and auxiliary files are stored in the user home directory

User home directory/.magicdraw/version.

Information about this location you may find in the MagicDraw About screen, Info tab (Help->About->Environment)

The "Help" may not be started because another application is using "Help" port. You may see this in the helpserver.log file, which is located in MagicDraw installation directory. If the server port is already in use, the java.rmi.server.ExportException appears in this file. To change Help port, you need to invoke the "Environment Options" dialog from the "Options" main menu. On the appeared dialog, "General" tab change the "Help Server Port", submit changes and try to invoke Help again.

Reasons why you cannot invoke the Help can be the following:

1. There is no reference to the topic, or a particular topic does not exist in MagicDraw Help. If a reference to the topic is broken, you can start the MagicDraw Help manually:

1.1. On the Help menu, click Help Content. The MagicDraw Help opens.

1.2. Browse in the help content or use a keyword to search for a particular topic.

Please let us know about broken links by contacting our customer support.

2. The communication with a server through Remote Method Invocation (RMI) is broken. Please do the following:

2.1. Open the* file. You can find the file in \bin.

2.2. To the JAVA_ARGS line, add a value -Dnostubfixing\=true, as it shown in the following example:

JAVA_ARGS=-Xmx1200M -XX\:PermSize\=60M -XX\:MaxPermSize\=200M -Dnostubfixing\=true

If the problem still persists, please contact our support team and attach the following files:
