HALion_Sonic_SE_3.5.10 installer crashes

I was having problems with HALion_Sonic_SE_3.5.10 not having any instruments loaded, so I uninstalled Cubase LE AI elements 12 and reinstalled it. However, when reinstalling HALion_Sonic_SE_3.5.10, the installer crashes. I am using windows 11. Does anyone know how to solve this problem?

Same problem with my Halion se 3.5.10. Starts to install but then install screen just disappears. Same problem with Groove Agent se 5.1.10. Using windows 11. Any ideas, raised support request with Steinberg over 2 weeks ago still no response.
