Unable to install Enterprise Workbench v3.8 Beta-1 [Closed]

Installed Eclipse M9 build on Linux system (previously using M8 build with MyEclipseIDE). Attempting to install EnterpriseWorkbench v3.8 Beta-1, but the installer won’t let me specify the Eclipse directory. The dialog box says:

… It should be named ‘eclipse’ and will directly contain a file called .eclipseproduct”

I renamed the directory containing eclipse, in case that was the issue, although I did not want to do that. However, there is no file called “.eclipseproduct”. I have run Eclipse M9 from that directory succcessfully, so that works. A directory listing for the eclipse directory shows:
