Hi,

I installed SWT Designer and WindowBuilder, both completely, from http://dl.google.com/eclipse/inst/d2wbpro/beta/3.7 into Eclipse SDK 3.7M6 on Ubuntu 10.10.
When trying to open the Editor's Design tab, I get the error below. Any advise how to fix this?

Thanks in advance, Ralf

That is weird. It looks like an incomplete install. Can you try installing it again?
