HALion Sonic SE 3.5.10 stand alone crashes on startup


HALion Sonic SE 3.5.10 crashes at startup with the attached error dialog. It’s in Swedish but says “Can’t find procedure start address of AdjustWindowRectExForDpi”.

Operating System: Windows 8.1 Pro
This happened after trying to install Cubase 12 Pro, but realizing the OS wasn’t supported. Uninstalling everything Cubase/Steinberg and trying to reinstall Cubase 11 Pro with HALion Sonic SE 3.5.10 and HALion content.

Cubase 11 Pro and HALion was working before attempting to install Cubase 12 Pro.

Please check the System requirements

I only find requirements for Cubase 12 on that page. Where do I find requirements for Cubase 11?


Here, for example, are the system requirements for Cubase 11 pro.

So I guess it’s more weird that Cubase Pro 11 worked on my Windows 8.1 before. I must have missed the updated OS requirements when buying an update at some time.
