Netbeans Tools->Plugins empty

Hello All,

I am running:
Product Version: NetBeans IDE 7.0 (Build 201107282000)
Java: 1.6.0_23; Java HotSpot(TM) 64-Bit Server VM 19.0-b09
System: Windows 7 version 6.1 running on amd64; Cp1252; en_US (nb)
Userdir: C:\Users\aparikh\.netbeans\7.0

When I go to Tools->Plugins, 'Updates', 'Available Plugins', 'Installed' tabs are empty.
When I click the 'Reload Catalog' button, I get the following error message (lower right hand corner red icon):
java.lang.NoClassDefFoundError: org/netbeans/updater/XMLUtil

I don't see any solution on the internet.

Please help.

I suspect a failed installation. I would uninstall it, wipe out the installation directory and settings directory, download again, verify the checksum, and install again.

(The missing class should be in platform\modules\ext\updater.jar in your NetBeans installation)

I have this NB installation for quite some time and I have been updating it.
I have the platform\modules\ext\updater.jar in the NB installation...

Anyway, if I was to uninstall and reinstall, which one is the settings directory?
Is it the Userdir: C:\Users\aparikh\.netbeans\7.0?
Installation dir is C:\Program Files\NetBeans 7.0
My project dirs located under C:\NetBeans will be OK, right?

The setting are in the userdir.

Your projects should be safe, they will not be deleted.

have this NB installation for quite some time and I have been updating it.

This could explain it. I use Eclipse and NEVER let Eclipse install any updates or patches. I used to and always ended up with an unusable mess. Ever since I stopped doing that life have been wonderful.
I agree. Here's the link: http://aspose.com/file-tools
