2026 won't load *.ivb via Settings or MS VBA window

[BrandonBG]

I'm migrating from 2025 to 2026 on Windows 10 and all customization appears to transfer correctly except for the VBA project.

I'm using a custom VBA project "Inventor.ivb" that's been in service since version 2020, and Inventor will not *load* the project via Settings or manually via the Microsoft VBA "Load Project" menu.

I've tried loading the default 2026 installed VBA project, and that does nothing as well. No errors, no prompts, just nothing happens when clicking on the *.ivb files.

I'm stuck on how to debug this.

I've tried rebooting, closing all applications that may run VBA, Windows update, updating VBA via the 2026 download below, and I can't tell if the issue is with Inventor or with VBA.

Have you been able to correctly install the vba module for Inventor 2026?

[BrandonBG]

The VBA module for Inventor 2026 installs with no issues.

I re-installed Inventor 2025 to see if I could recreate the behavior, but VBA loads correctly in 2025.

Anyone else seeing issues loading VBA files in 2026?

[BrandonBG · Accepted solution]

I didn't expect this result, but I have functional VBA in 2026. Here's the process:

Close 2026.

Install 2025.

Open 2026.

Load VBA project. It's there and it works.

Close 2026.

Uninstall 2025.

Open 2026.

Load VBA project. It's still there and it still works.
