Hi Ladybug Forum!!

I am running into an issue installing with Pollination.exe

[17:04:43.897901 ERROR] [openstudio.workflow.OSWorkflow] Found error in state ‘OpenStudioMeasures’ with message: 'Failed to load measure ‘FromHoneybeeSimulationParameter’ from 'C:/Program Files/ladybug\_tools/resources/measures/honeybee\_openstudio\_gem/lib/measures/from\_honeybee\_simulation\_parameter/measure.rb

Has anyone run into this issue before? This error appears after running ModeltoOSM and after redownloading with Pollination.exe

Hi @washingaton are you using the food4rhino installer or the pollination installer?

Hi @TrevorFedyna I used the pollination installer.

I was checking this forum post: [Solution exception:No file was found at C:\...\openstudio\out.osw - #17 by physee](https://discourse.ladybug.tools/t/solution-exception-no-file-was-found-at-c-openstudio-out-osw/19957/17)

It seems like Pollination installs incompatible versions of Openstudio and EnergyPlus.

Does anyone know how to downgrade openstudio and Energy Plus?

Hi @washingaton ,

The pollination installer is working correctly and OpenStudio comes with a compatible version of E+ so there will never be a version conflict there. The problem happens because you are using an old Grasshopper script with an old “Model to OSM” component in it, which is not compatible with the latest pollination/LBT-Grasshopper version.

I suggest running the [LB Sync Grasshopper File](https://docs.ladybug.tools/ladybug-primer/components/5_version/sync_grasshopper_file) with your old Grasshopper definition so that it will be synchronized with the components you have currently installed. If everything has run successfully, you’ll see that the “Model to OSM” component should be 1.8.3:

Hi @chris !! Thanks for responding so quickly, This did work for ModelOSM!! However, when I run the sample script “outdoor\_comfort\_under\_a\_tree”

I get this error, even after syncing the file?

Yes, there was a bug that @Byron reported today and I fixed a couple of hours ago:

> I know I might be running ahead but I updated my LBT to check the new functions …using OS 3.9 which broke some of my components.

> There was no way to go back and run the HB\_UTCI component without editing the code.
> Within the utci\_comfort\_map\>flow\>dependencies\>energy\_simulation.py I had to remove "\_--check-model\_" from line 191 to make it work.

You can get the fix on your end now by running the LB Versioner component.
