OpenMEP package installation

Hello everyone, this forum is being of great help to me. But I’m facing a small problem installing the openmep package. It is available on github and even following all the steps presented by the developer, after its installation the following message appears on my dynamo:

"Dynamo.Exceptions.LibraryLoadFailedException:
Failed to load library: C:\Users\cbpir\AppData\Roaming\Dynamo\Dynamo Revit\3.0\packages[OpenMEP](https://forum.dynamobim.com/t/openmep-package-feedback-thread/)-2.0.25.62550

package without a header. Ignoring."
Could someone tell me what this problem is? I can’t find where I can change it. I spoke to the developer and theoretically the version is correct.

@jacob.small any update from team in configuration requirement recently in version 3.0 ?

Nothing has changed as far as I know. I have the same configuration of my pkg.json files from Dynamo 2.10 to 3.4.

Considering it isn’t impacting others (as far as I know anyway) my guess is it is a system specific issue.

Hello! Could you tell me if there is anything I can do to try to solve this?
