Cannot create Roo project on fresh install 2.8.1

After project wizard ends and I click Finish I get the following in Error Log:

Project facet grails.app has not been defined. It is used in plugin com.springsource.sts.server.tc.core.

No project structures folders are created. Any advice would be appreciated.

EDIT:
I actually tried to install Grails from Extensions tab, however it failed with the following error:

Problems occurred while performing installation: Operation details

Hi!

Can you describe the steps to reproduce this error? I guess you don't have a fresh STS installation from the STS distribution packages, but instead an Eclipse installation with STS installed afterwards yourself, right?

Please let us know what to do to reproduce this (starting from the STS installation would be great), so that we can try to find the problem.

Just a side note: If you are running STS on a Windows machine, please take care NOT to install STS into the "Program Files" directory, but instead your users home or a subdirectory of that (special access permission problems under Win7).
