SDK 1.3.4 3DS Max scene converter broken

Version: SDK Core 1.3.4

Frequency: Consistently

Severity: Blocker

Bug description:
When opening an FS2020 project in 3DS Max 2024 with the FS2024 SDK 1.3.4 installed, the update popup doesn’t come to life, making it impossilbe to automatically update the scene to FS24 materials. Instead the stock Max scene converter shows up.
Rolling back to SDK 1.2.4 solves the issue.

Repro steps:
Open any MSFS2020 project in Max 2024 with only the MSFS2024 core installer 1.3.4 installed (no FS2020 SDK installed).

Hi Mathias,

I experience the same issue. When I try to run the scene converter manually, it says that the scene is already converted to FS24. Now that we know it’s a regression, it should hopefully be an easy fix for the SDK team.
