I am running eclipse 3.5 (ganymede) on win7x64 and tried installing gwt designer (both the latestBuild and the 2010.05.18 Release 7.5.0)
I get this error. Seems like it wants x32 only.
Cannot complete the install because one or more required items could not be found.
Software being installed: GWT Designer Core 7.5.0.r35x201005180224 (com.instantiations.designer.gwtcore.feature.feature.group 7.5.0.r35x201005180224)
Missing requirement for filter (&(osgi.os=win32)(osgi.ws=win32)): GWT Designer Core 7.5.0.r35x201005180224 (com.instantiations.designer.gwtcore.feature.feature.group 7.5.0.r35x201005180224) requires 'com.instantiations.designer.gwt.hosted.1_6.ie [7.5.0.r35x201005180224]' but it could not be found
