Python Heads Please spread the love

Hi all
I have a few plugin that require Python, They used to work before I a fresh version of windows7 64bit.
Plugins like Gear mbfeathers require Python am getting this error:
# File "C:\Program Files\Autodesk\Softimage 2012 SP1\Application\python\Lib\site-packages\win32com\client\dynamic.py", line 538, in __setattr__
# self._oleobj_.Invoke(entry.dispid, 0, invoke_type, 0, value)
# COM Error: Unexpected failure. - [line 39 in C:\Users\Ben\Autodesk\Softimage_2012_SP1\Addons\mbFeatherTools\Application\Plugins\mb_FeatherToolsPlugin.py]
So How I installed python and the files i used would be like this:
1) I downloaded the file Python-2.6.8 from the python site, and extracted to the root of my c drive. Could not find a .exe version
2) I added the python folder (e.g. C:\ Python-2.6.8) to the PATH environment variable, system properties/Advanced tab/ environment variable
In the System variables section
PYTHONPATH C:\ Python-2.6.8
3) in stall pywin32-212.win-64-py2.6
4)switch xsi to script python and tick off use xsi python
5) restart
6) open xsi and all should work or not in my case!!!!
Is this the right way are these the right files can any one spread any light on this
In my plugin list there are still some scripts with red warning triangles
All the best Ben

The first function should be commented out, only the protoype and return should remain:
def __WrapDispatch(dispatch, userName = None, resultCLSID = None, typeinfo = None, \
UnicodeToString=None, clsctx = pythoncom.CLSCTX_SERVER,
WrapperClass = None):
"""
Helper function to return a makepy generated class for a CLSID if it exists,
otherwise cope by using CDispatch.
"""
#assert UnicodeToString is None, "this is deprecated and will go away"
#if resultCLSID is None:
#try:
#typeinfo = dispatch.GetTypeInfo()
#if typeinfo is not None: # Some objects return NULL, some raise exceptions...
#resultCLSID = str(typeinfo.GetTypeAttr()[0])
#except (pythoncom.com_error, AttributeError):
#pass
#if resultCLSID is not None:
#import gencache
## Attempt to load generated module support
## This may load the module, and make it available
#klass = gencache.GetClassForCLSID(resultCLSID)
#if klass is not None:
#return klass(dispatch)
# Return a "dynamic" object - best we can do!
if WrapperClass is None: WrapperClass = CDispatch
return dynamic.Dispatch(dispatch, userName, WrapperClass, typeinfo, clsctx=clsctx)
Maybe this might work.

Also, I wouldn't recommend the forceful dispatch "fix". There is so very little these days that still has dispatching problems that it's not worth the bother, not to mention the divergence from standards if you ever want to release anything, and a performance hiccup in some uses.

It looks like you might be missing ActiveState's pywin. Did you install that?

Like Raff and Eric said, don't patch it. Use the dispatch fix coming with pywin32.
