I downloaded netbeans IDE 6.9 for windows. But I can't find installer option. Looked at http://blogs.sun.com/geertjan/entry/generate_a_netbeans_platform_installer where it says that there is one, also on http://netbeans.org/community/releases/69/index.html it says that there is new feature "NetBeans Platform-based applications generate installers for most common operating systems".
Why I don't have one?
The downloaded file should be a .exe which launches the installer when run. You may have downloaded the wrong version
If you downloaded a zip, it may be the non-install version. You can then simply run it from bin/netbeans.exe
This property page is associated with a 'Module Suite' project and a 'NetBeans Platform Application' project.
After you create a 'NetBeans Modules->Module Suite' or 'NetBeans Module->NetBeans Platform Application' project, you need to MANUALLY ACTIVATE the "NetBeans Plugin Development" module.
Trigger the Plugins item on the Tools menu.
Select the Installed view.
Tick the Show details check box.
Scroll through the list to NetBeans Plugin Development
Tick the check box
Press the activate button
I opened http://netbeans.org/bugzilla/show_bug.cgi?id=189026 to request that the manual activation seems like a usability big.
