Pixinsight installation failure 1.8.5 on Windows 10

[psingh4]

I am having trouble installing PixInsight 1.8.5. I uninstalled 1.8.4 which I have been using for some time.

I get the error that:
The PixInsight Setup Wizard ended prematurely.

Please see the attached screenshot.

Does anyone know any workaround for this?

O/S Windows 10, 64-bit, latest updates

Can anyone help please? Do I need to get back to 1.8.4? I will be able to troubleshoot this if I can find the installation logs.

I do not want to have to wipe Windows 10 and re-install whole o/s when all other apps are just working fine.

Figured it out. Windows 10 had done an installation of security updates - but had not restarted. Once I restarted, the installation went through normally.
