Could you try to reboot your computer and then run atk?

thanks your suggests and I tried but nothing change. Process setup is normal.
I don't realy know that error.

• Have you installed any other version of ATK
• Did they work ?
• What versions of ATK do you have installed?
• Have you set the environment variables PYTHONPATH and/or PYTHONHOME?

Do a simple test to check whether this is related to the python included in ATK:
i) enter the command mode of ATK 10.8:  Start--->Run--->type command "cmd" ---> go to the installed path of atk, e.g.: C:\Program Files\QuantumWise\atk-10.8.b1\atkpython\bin---> run "atkpython.exe". In this step, the python included ATK will be launched actually.
ii) type the following two lines

  for i in range(5):
       print i

", its interface looks like:

In [1]: for i in range(5):
   ...:     print i
   ...:

If it normally gives the following screen printing,

this means that your configuration of ATK is OK. Otherwise, if the error message of "<ERROR: 'dict' object has no attribute 'len'>" still appears, it means that the problem is related to the python, as discussed in the the following webpage:

The solution for such problem is also given on that webpage.

A possibility is that you have an existing installation of Python/iPython that is conflicting with ATK. Check your home directory (c:\users\username and/or your "My Documents" folder) for a folder called _ipython. Unless you have particular reason to keep it, delete it (in both places), and try to run "atkpython" again.

I typed:
 for i in range(5):
       print i
it interface looks like:
<ERROR: 'dict' object has no attribute 'len'>
