If you get this message when you attempt to register the AMCP plug-in (amcplugin.jpr):
Could not read manifest.file
The installer has renamed the amcplugin.jar file to amcplugin.jar.installed to avoid overwriting existing files.
When you attempt to run registerAMCP from the command line, you see:
Error: Unable to find the AMC Plugin binary. Please check that $SYBROOT has been set correctly and that the file /AMCP/lib/amcplugin.jar' exists.\n
Rename amcplugin.jar.installed to amcplugin.jar.
