Cw 4.0.1 connectivity issue with HW


I try to run CW version 4.0.1 because I want to use the capture tool. But unfortunately without success. After performing of two lines of code

import chipwhisperer as cw

I get the following error

Traceback (most recent call last):
File “”, line 1, in
File “c:\program files\chipwhisperer4\chipwhisperer\software\”, line 91, in scope
File “c:\program files\chipwhisperer4\chipwhisperer\software\chipwhisperer\capture\scopes\”, line 62, in con

raise Warning(‘Could not connect to “%s”. It may have been disconnected, is in an error state, or is being used by another tool.’ % self.getName())
Warning: Could not connect to “NewAE USB (CWLite/CW1200)”. It may have been disconnected, is in an error state, or is being used by another tool.

I am using Windows 10 machine, chipwhisperer SW installed using 64-bit windows installer. The part of the installer is winpython v. 2.7.13, chipwhisperer python API v. 3.5.3 (actually this version you will not find in official pip repositories but is part of the CW installer). Connected HW is CW Lite. The CW Lite board appears under windows as USB serial device.
Also tried different CW python API versions: v.3.5.0 and 3.4.1 but in those versions performing ‘cw.scope()’ results in ‘object has no attribute scope’.
Where can be the problem? Did you someone succeed in installing the old version 4.0.1?
