nsanderson asked a question.
Is Windows Server 2025 identified as a OS type in SYSINFO.WINNT?
Using InstallShield 2025 R1, we can see that Server 2025 is now included as an OS type.in the check box screen.
However, it looks like the SYSINFO.WINNT values haven't been added to in order to support identification of Server 2025 as a valid OS?
Are there plans to add Server 2025 into SYSINFO.WINNT or is there a separate way to identify the OS?
We have tried using 2025R2 but that contains a catastrophic bug with the licensing dialog when stepping through an install created with R2 (this has been raised and confirmed as a valid bug).
So, in short, the answer is no. I've decided to work around this shortcoming by rewriting our OS check routine to ignore any old operating systems (7, 8, 8.1, etc.) and allow new ones (10+) through.
