Unsupported Nullsoft Installer

[AntumDeluge]

I came across an installer that displays as "Nullsoft Install System v", but Universal Extractor is unable to handle it. Is it just a newer version that isn't supported yet? It looks like the version number isn't even embedded into the installer wizard.

The executable can be found here labeled as "antimicrox-3.2.5-AMD64.exe".

I sent a report with the feedback form. Don't know if it got through.

Scan result:

I opened it with 7z from here: https://github.com/Wilenty/7-Zip-X64-X86-with-Extracting-NSIS-script

Same is true for FLStudio installer: https://support.image-line.com/redirect/flstudio_win_installer which identifies itself as Nullsoft Install System v16-Apr-2020.cvs Also cannot be opened properly using 7zip with nsis support.
