Simon,
I’ll point out that although we could create a Solaris installer, we don’t do it because we have no way to test our product on Solaris. As a result, it’s an unsupported platform. However, if you’re inclined to manually install MyEclipse on Solaris please fee free to do so, but please remember that any problems you encounter must be reproducable on one of our supported platforms for you to get any support for it.
