Unable to call COM object with elevated privileges

Question

I am working on a Python script that interacts with a COM object of Autodesk Inventor. I can create this object like so:

>>> import win32com.client
>>> win32com.client.Dispatch('Inventor.Application')

When I am running it normally, it works fine. However, when I run it in a shell with admin permissions I get this error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\site-packages\win32com\client\__init__.py", line 95, in Dispatch
    dispatch, userName = dynamic._GetGoodDispatchAndUserName(dispatch,userName,clsctx)
  File "C:\Python27\lib\site-packages\win32com\client\dynamic.py", line 114, in _GetGoodDispatchAndUserName
    return (_GetGoodDispatch(IDispatch, clsctx), userName)
  File "C:\Python27\lib\site-packages\win32com\client\dynamic.py", line 91, in _GetGoodDispatch
    IDispatch = pythoncom.CoCreateInstance(IDispatch, None, clsctx, pythoncom.IID_IDispatch)
pywintypes.com_error: (-2147221164, 'Class not registered', None, None)

To try to find the cause of this issue, I followed the steps detailed here. I created this VB Script,

set obj = CreateObject("Inventor.Application")
MsgBox TypeName(obj)

And ran it with both 32 and 64 bit engines under varying permissions:

• User permissions- Script runs correctly both times
• Admin permissions- Script throws error both times

I also checked HKEY_CLASSES_ROOT in my registry, and the application is there and spelled correctly. How can I resolve this?
