WindowsError: [Error -2147221163] Interface not registered

[Peck117]

Hi there,

I am trying to use the toolbox but get the error below. I am a complete novice when it comes to python but I think the comtypes are correct. Using ArcGIS 10.6 and comtypes 1.1.7

Any help would be very much appreciated.

Traceback (most recent call last):
File "C:\Users\peckc\OneDrive - University of Manitoba\Documents\ArcGIS 10.6\mapqonverter-master\mapqonverter.py", line 159, in

Failed to execute (Mapqonverter).

Hi Peck117,

if the interface is not registered, somehow comtypes can't load the arcmap libraries.
There can be many reasons for that. The path looks allright: C:\Python27\ArcGIS10.6\lib\site-packages\comtypes

Unfortunately it's hard to tell, where the problem lies. You can try installing mapqonverter with this setup: https://files.wheregroup.com/s/ksCiBk3SWcMBxsf

Perhaps this helps.
