[soapui-user] soapui installation problem on mac os 10.5.8

[Матюшкин И. <i20...@ya...>]

SoapUI 4.0.1 installer doesn't start on MacOS 10.5.8 without any error messages. Another times when I tried to start SoapUI installer MacOS has shut down unexpectedly. This result was even I tried to install earlier SoapUI's versions. I think the reason should be searching in the system configuration, but it very near to default. What can be a reason of this installation problem?
Thank you for a help.
