Hello,
I have 3 versions of Inventor installed (2018, 2022, 2025). I created a project. In the references, I have only “Autodesk Inventor Object Library” of 2018 to choose from. I need to change it to 2022 because I can't read files created in Inventor 2022. How can I change it?
Here are all versions located:
C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Autodesk.Inventor.Interop
Regards,
Arthur Knoors

How do I know which version to choose? I selected the latest one I have (v4.0_29.0.0__d84147f8b4276564), unfortunately I still can't read the parts created in versions 2022 and 2025. I can only open the file from version 2018. I also tried selecting other references but the effect is the same. Shouldn't it be that the latest file, opens all previous versions?
I recommend you to use folder structure similar to this sample
Development\ - contains all development data
Development\out\ - Final builds (binaries, MSI packages, etc.)
Development\ref\ - Copy of all third party libraries used in project.
Development\src\ - All source code files
Documentation\ - files which describes the project, like specification, help files, etc.
Realization\ - data for implementation to end user, support, data sets. etc.
To the ref\ folder copy the files:
autodesk.inventor.interop.dll - Primary interop library for Inventor API
autodesk.inventor.interop.xml - Documentation file for intellisense.
In the project remove the default reference and add new to this copy in ref\ folder.
In future if you want to update inventor version, you can just replace the file in ref\ folder.
