Grasshopper Loading Errors at Start

[sebandraos]

Description

When opening Grasshopper a series of error messages appear in a pop-up often listing TargetInvocationExceptions and/or FileNotFoundExceptions, or nothing shows up in Grasshopper.

Cause

This is almost always due to a corrupted installation or conflict with other plugins.

Help to Fix

1. Please zip C:\ProgramData\HAL and upload it as a comment as this contains everything we need to examine the installation failure. Please also include the OS and what version of the OS you're running, a copy of the errors, and which installations and versions that you have installed. The latter can be found via the installer.
2. Look at the Rhino console and see if any errors are present. If so, it is likely there is a conflict with another Rhino or Grasshopper plugin. See this issue for more details.

Workaround

1. Once you have zipped the file and uploaded it so we can try and find the root cause of the issue you can perform a clean uninstall and reinstall the Framework. Please make sure that Windows is up to date.
2. If that doesn't work, try deactivating all Rhino and Grasshopper plugins (especially those that you recently installed if this is a new issue). See this issue for more details.

Hi @julienenpc
Are you sure your Windows version is correct? 1607 EOL'ed in April 2019. If so, I recommend updating your Windows installation and retrying. The update will likely include an updated .NET Framework version that might fix some of the issue.
Thanks

Je suis toujours en version 1607 après la mise à jour, c'est peut être ça le problème ?
#69 (comment)

I just saw the DSI, we updated the computer and we are still in version 1607, there is no new update to do.
We tried to install it without the antivirus, and still the same problem. They don't know where it comes from.

[sebandraos]

Ok, try installing the latest versions of .NET Framework and reinstalling the HAL Robotics Framework

[julienenpc]

It's working ! Thanks a lot !

@dominikreisach Is anything written in the Rhino command bar during loading Grasshopper? Can you also please confirm that HAL.ghlink is present in the %appdata%\Grasshopper\Libraries folder?

[dominikreisach]

The file is in the folder. Found the error message in the command bar:
HAL: Method not found: "Unity.IUnityContainer Prism.Unity.Ioc.UnityContainerExtension.get_Instance()"

I guess that means conflicting dependencies (probably Enscape) and therefore #22 ? :)

[sebandraos]

@dominikreisach Correct. If you have Enscape installed then that will definitely be the problem. Unfortunately that is an insurmountable problem at the moment so you'll need to deactivate Enscape whilst using HAL.
