RDM manager doesn't start after updating to any 2025.* version

Hello Luca,

Is there any additional information available in the Event Viewer?
Which OS build are you using? (Start => cmd => winver)

Hi, I'm using 22H2 Win10:

I've found this in the Event Viewer:

Hello Luca,

Alright, thank you for the details! The main reason RDM isn't working anymore is that your OS is outdated. Therefore, it seems .NET 9 is not supported or is not working as expected.
https://support.microsoft.com/en-us/topic/april-11-2023-kb5025221-os-builds-19042-2846-19044-2846-and-19045-2846-b00c3356-baac-4a41-8342-7f97ec83445a

I would suggest upgrading to a newer OS release.

Thanks for your answer! I plan to switch to Windows 11 in the coming months, but for now I’ll downgrade to the latest 2024 version.
Thanks
Luca

Maybe you can just upgrade your Windows 10 to a newer build? My version is as follows (although it's not Enterprise but Pro), compare it with yours. Ask your admins if you can update to this version, it'd solve your issues with .NET and RDM. I have just been installing monthly updates to get to this build.
