Has anyone ever got a message like this when trying to start TopBraid
Maestro Edition? If so how do you fix it?
Thanks

Patrick,

I've seen similar messages if a few bytes got mangled while I was
downloading a TBC distribution. I would suggest downloading again, comparing
your two downloaded files (at least compare the file size, but if you have a
diff utility that will tell you if there are differences even if the file
sizes are the same), and re-installing with the new download.

Hi Bob,

Patrick has downloaded and rerun with the same error occurring. Is it
likely that java config may cause this? If so what should patrick
check before installing?

Cheers
Derek

Derek,

Can you tell me exactly which distribution he downloaded and how big, in bytes, the downloaded version was? 

thanks,

Bob

Patrick, Derek; It's also vitally important to let us know what
version and edition of Composer is being used, as well as the OS. For
example, Unix-based systems often default to Open JDK, but Sun/Oracle
JDK is required for Composer (see http://www.topquadrant.com/products/supportedPlatforms3.5.html).
This could be a potential issue, as there may be differences in class
loaders that would cause the error message.
