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.

Hello,
I Couldn't upload the HAL folder zipped (too big) so here it is

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

[julienenpc]

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

[julienenpc]

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 !

[sebandraos]

@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.

[dominikreisach]

@sebandraos Thanks. It is working now!

Hi,

Linked to the issue #120 you will find details below :

ZIP : https://we.tl/t-GlvaQnr3oT
OS : Windows 10 v21H1 Professional build 19043.1526
Rhino : v6 SR 35 (6.35.21222)
HAL : 1.4.22-beta

I think it appeared after installing this plugin :

https://github.com/andrewheumann/jSwan

Thanks.

[tristangobin]

This is probably related to this issue #22 since it seems using a different (Newtonsoft.Json) version.

[xPhilippeRoux]

Thanks it worked with the "COFF" trick.

[tristangobin]

As it seems resolved I closed this issue. Thank you for using our software and reporting issues.

[sebandraos]

Reopened as mistakenly closed

Hi HAL not loading at all, had no issues before.
HAL.zip.

[thibaultschwartz]

Hi @akaFlux, your installation log does not show any error, do you have an error messages showing up in rhino when starting Grasshopper? Did you run the setup with your user windows account or with another acount?
The ghlink was added there: C:\Users\josel\AppData\Roaming\Grasshopper\Libraries\HAL.ghlink

Hi @thibaultschwartz I have no errors messages, I do not see any HAL texts in the GH loading bar in the spalsh screen (I used to), I have ghlink in the libraries. I even copy HAL.McNeel.Grasshopper1.Client to the libraries folder to see if was loading and at least ask me whichone I want to load.

I had this isssue before and I format my computer an the problem solved, I did format it again and is not working this time. I also have HAL installed on my laptop, and works fine.

EDIT:
I uninstall and install it again, now I see a text in the loading bar with the HAL.McNeel.Grasshopper1.Client (i think so its a bit fast). But still nothing loaded.

[thibaultschwartz]

Hi @akaFlux, it really feels like you are not using the same account than the one you used to install HAL, or that you manually installed grasshopper somewhere else than its default location.

• Never copy HAL files manually anywhere, the setup is much more complex. That's why there is a dedicated installer. The only thing that can be copied is the ghlink, but it should already be in you libraries, as I can see in your log it was created.
• You say "I see a text in the loading bar": then please copy it here. In rhino you can make the command bar as high as you want and you can open it as a separate window using F2.
• Are you sure you are using the same user account to launch rhino? For exemple: are forcing the execution as administrator, or did you execute the HAL installer as administrator instead of your regular user privileges?

[AngelinaGaripova]

Hey!
I have an issue - HAL plugin disappeared from GH after Rhino 7 Update
The error is:

The system cannot find the path specified. (Exception from HRESULT: 0x80070003)
HAL: Method not found: 'Unity.IUnityContainer Prism.Unity.Ioc.UnityContainerExtension.get_Instance()'.

I have reinstalled everything from scratch several times and blocked Enscape plugin, but it is still not working.

ZIP file https://www.dropbox.com/s/n9326vgfaae387b/HAL.zip?dl=0
Rhino version 7 SR19 (7.19.22165.13001, 2022-06-14)
Windows Home 21H2 OS build 19044.1766

During the first installation, there was also a similar error, after which I blocked Enscape and everything started to work. But now after Rhino update everything stops working again.

Thank you.

[sebandraos]

Hi @AngelinaGaripova ,
Your installation looks fine. I have just updated Rhino to 7.19 on my end and everything seems to be loading ok so it seems likely that a plugin other than Enscape is conflicting with the Framework.
Do you have any other plugins installed in Rhino and/or Grasshopper?

[AngelinaGaripova]

Hi @sebandraos <https://github.com/sebandraos> Yes I have other plugins installed, below are the pictures of them

HI Angelina,
There is no way to identify the clashing plugin from theses screenshots. I would suggest you disable all other plugins using the GH loading settings to test if it's coming from a GH plugin at all:

[thibaultschwartz]

Alternatively, run a search in your GH Library folder and look for "prism" or "unity"

[AngelinaGaripova]

Thank you @thibaultschwartz !
I have tried to disable the solver for all the plugins and remove Heron and LunchBox from PackageManager - did not help.
Also, a search by "prism" or "unity" in GH Library gave nothing.
In the end, I uninstalled all Unity and Enscape apps from my computer and re-install Rhino and HAL from scratch and it helped.
I don't know what helped exactly, but everything works and the error is gone.

Hi,

I'm having a new error, still linked to jSwan. However the "COFF" is still enabled in the Developer Settings.

The error message is :

An error occured during GHA assembly loading:
Path: C:\Users\phili\AppData\Roaming\Grasshopper\Libraries\jswan_0.gha
Exception System.IO.FileNotFoundException:

Thanks.

[thibaultschwartz]

Hi @xPhilippeRoux,
This is definitely a Jswan issue, most likely a clash in dependencies (different versions of Newtonsoft.Json being loaded).

[xPhilippeRoux]

Thanks @thibaultschwartz.

I went on andrewheumann/jSwan#9, downloaded Newtonsoft.Json.dll & placed it in the Grasshopper folder. The error is now gone & jSwan plugin works fine.

However nothing on HAL Framework side. I uninstalled & installed again, same result.

Any idea on this ? HAL plugin seems not installed whereas it is. My previous ZIP stays up to date.

[sebandraos]

Hi @xPhilippeRoux ,
You have exactly identified the problem but unfortunately it's not resolvable - see #22 for more details.

[xPhilippeRoux]

Hi @sebandraos ,
Could you elaborate a little ? I know that both plugins worked fine on my machine (with the "enable COFF" technique), and still work fine on other's.

Are you suggesting to remove jSwan so that HAL can run, and that it is the only solution ?

[sebandraos]

@xPhilippeRoux , this is a classic issue with plugin-type software. We and jSwan have dependencies on the same library - Newtonsoft.Json - but rely on different versions. Which one will work is purely dependent on the loading order of the plugins, the first one to load will load its version of Newtonsoft.Json and that will break the other. If others have both plugins working simultaneously then it's worth looking at what their COFF settings are and what other plugins they have which might be affecting the load order but it would be pure luck if it works.

One option which might work is to trick jSwan by replacing their dependency with our version of Newtonsoft.Json from C:\ProgramData\HAL or vice versa. That is definitely not a supported scenario for the HAL Robotics Framework or jSwan but it might work in your case.

HAL.zip

Hello,
Corresponding to the above mentioned error about which I emailed you today, I am attaching all the required information.
I was obliged to remove the 'Extensions' folder from the zip folder, as it was too heavy to be attached here.
Thankyou very much

[sebandraos]

@krittikaw8 I can see that MathNet is definitely installed so it looks like this is a plug-in conflict as per #22 .
Has our plug-in ever worked? If so, did you install anything recently that might align with when it stopped working?
If not, which other Rhino and Grasshopper plugins have you got installed?
Try deactivating all of them and see if everything works then. If not, then we'll need to dig deeper.

This is how you can disable Grasshopper plugins:

HI Angelina, There is no way to identify the clashing plugin from theses screenshots. I would suggest you disable all other plugins using the GH loading settings to test if it's coming from a GH plugin at all:

And you can do the same for Rhino from the Rhino Options -> Plugins Window. You can filter installed plugins by "Plugins that don't ship with Rhino" to find likely culprits.

You'll need to restart Rhino for that to take effect.

[krittikaw8]

Hello,

Thankyou very much for your answer.
It indeed helped fixing the issue.

I removed MathNet and finally it works.
HAL used to work perfectly fine before I recently installed some more plug-ins, so I guess that's where the problem occured.

Thankyou very very much for helping me out.
