Chemplugin path error

Recommended Posts

Good day,

I have switched to a new computer and now I cant get chemplugin to run on it


This is the error message in python (spyder):

FileNotFoundError: Could not find module 'chemplugin' (or one of its dependencies). Try using the full path with constructor syntax.


The paths look ok (the same as on old computer)


The license is OK (as CP is now also part of GWB Pro?)



Thanks for your help.

Hi Johan,

The activation looks fine. If you still have the standalone ChemPlugin SDK installed (under Program File\ChemPlugin), I would start by uninstalling that. Then, try reinstalling GWB Professional. Your original download link should download the latest version, which is currently 17.0.2. I would leave the option to set PATH and PYTHONPATH set. Then, reboot your computer to make sure your environment variables are updated. Then check not only your PYTHONPATH, but also your PATH environment variables. Then try to run your ChemPlugin client again.

If you're getting the same error, can you please open the command prompt, type “python”, then issue the following commands and provide screenshots?

import os,sys
print(os.listdir('C:\\Program Files\\Gwb\\src'))
