Do not see UCOSII folder

I have several versions of Quartus/NiosII installation installed over last couple of years... I have 4.0, 4.1, 5.0 and recently 5.1 http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif

Today it was the first time I wanted to build an example application for NiosII using MicroC/OS and I started to read the section 8 of handbook dedicated to this OS.

What I have realised is that I do not have the folder c:/altera/kits/nios2_51/components/altera_nios/UCOSII on my 5.1 installation path. The folder exists in version 5 and 4, but not in 5.1

Why can it be this way?

What can I do about it?

Will simple copying this folder from 5.0 path to 5.1 do the trick ?

I have noticed also, I do not have the UCOS option in the configuration of the system library in Nios IDE. It must be somehow related to this.

Please help http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif
