Could not find part of the path ... \Microsoft.NETCore.App\8.0.5\System.Runtime.dll

Hello All

I have been getting this error message occasionally since upgrading to Inventor 2025. 

Maybe once a week or so. A restart of Inventor fixes it, but I would like to know how to make it go away for good. 

It is missing "C:\Program Files\dotnet\shared\Microsoft.NETCore.App\8.0.5\System.Runtime.dll"
The folder 8.0.5 does not exist on my computer but I have 8.0.6, which is listed as the active version of .NET. 

Any pointers on how to resolve? 
Thanks

This looks like a issue in used references. Without the source code it is not possible to identify the issue.

But you can look if you don't reference System.Runtime.dll directly in your rule or external library.

The iLogic rule with the source code, has all lines commented out. It is no longer used. There is no direct reference in the code. 
I am wondering if there is an internal inventor reference to this dll somewhere. 
How would I check, and is it something I can access?

You can try to install the .NET 8.0.5 runtime from this direct link

Installed successfully, hopefully that clears it for good.

Hello. I wasn't sure if it was worth creating a new post, or extend this one. I'm having the same issue, except our .net directory is 8.0.8. We all got new workstations and have C:\Program Files\dotnet\shared\Microsoft.NETCore.App\8.0.10\System.Runtime.dll. It sounds like I can either fix the code for everyone, or everyone has to wait for IT to install 8.0.8 back on their computer. To me it sounds easier to fix the code, especially since we have other ilogic rules. Anyway, how do I determine how to update the code? Or is it possible to point the rules to the 8.0.10 directory?

Hello 
I don't think you will be able to edit the code to remove the dependency. Other more knowledgeable people can comment on this, but I thought the dotnet component is something iLogic requires to function and is not referenced in the rule itself.

I would suggest getting the dotnet version installed. Here is a link to the download page, just find the correct version you are missing and download and run the installer. 

Download .NET 8.0 (Linux, macOS, and Windows) (microsoft.com)
