From what I understand, GRC is bundled with the gnuradio 3.2 release.
So you shouldnt need to install this "GRC version 0.7" package. Use the
grc that comes bundled with gnuradio, anything else will have problems
working.
If your package manager cannot give you what you need, I recommend just
installing the gnuradio from source code

Gnuradio 3.2 as shown in Add/Remove Programs. How can i upgrade my GNU/GRC
installation to work with USRP2?

Wow, how did you find this ancient version of grc?
Anyway, here is the note from my website:
Please use the grc that is bundled with the current gnuradio master or
the gnuradio 3.2 release. It has a years worth of work and improvements
compared to the last versioned release of grc (0.70). In addition, the
grc bundled with gnuradio is guaranteed to evolve with gnuradio; whereas
the older non-bundled grc will stagnate and cease to be compatible with
newer gnuradio releases.

Hi,
I have a problem concerning USRP2. I am using GRC to make flow graphs but I can
not find USRP2 when I use USRP source block. When I run a simple program with
only two blocks (USRP source and Scope Sink) I get following error:
Verbose:
usrp: failed to find usrp[0]
Traceback (most recent call last):

RuntimeError: can't open usrp
I also tried using USRP Diagnostics in Help menu but it also does nt detect.
I run find_usrps through terminal and it works like,
00:50:c2:85:34:6f hw_rev = 0x0400
