Hi all,
We have tested HALion 6 and HALion Sonic 3 on Windows 7 and are happy to announce that the official support of Windows 7 has been added.
Please make sure that at least Windows Service Pack 1, Microsoft.NET Framework 4.0 and the W7 platform update (https://www.microsoft.com/en-US/download/details.aspx?id=36805) are installed.
