Error occurs during installation of Robot Framework with Python on Windows 7

Question

I have installed "python-3.3.0.msi" successfully and set up PATH as "C:\Python33;" on Windows 7. After that I tried to install Robot Framework by using "robotframework-2.7.7.win32.exe" (double click on the .exe file). At the last step of installation I found the following error:

File "<string>", line 35
    except Exception, err:
                    ^
SyntaxError: invalid syntax

I clicked on "Finish" button --> Installation wizard was disappeared. I set the PATH as "C:\Python33\Scripts". Then I checked the version by using the command "pybot --version" at command prompt. Below error was shown:

Traceback (most recent call last):

How can I solve the above error?

Looks like Robot Framework doesn't support Python 3 yet. You should try to use Python 2.7 instead. (Python 3 changes lots of things in the language syntax, including the syntax for catching exceptions shown in this traceback.) — Schnouki
@Schnouki: Thanks a lot. Yes, It has been solved by using Python2.7.3 instead of Python3.3.0 — Ripon Al Wasim
@Schnouki You should've written that as an answer, so the asker can accept it. — Qwerty

Robot Framework doesn't support Python 3 yet. You should try to use Python 2.7 instead. (Python 3 changes lots of things in the language syntax, including the syntax for catching exceptions shown in this traceback). So, follow the following installation steps:

Install Python2.7.3
Install robotframework2.7.7
set PATH as "C:\Python27\;C:\Python27\Scripts\"
Verify the installation by using the command "pybot --version" at command prompt. If everything is OK, the
following message will be displayed: "Robot Framework 2.7.7 (Python 2.7.3 on win32)"
