When attempting to install a the newest version of SolarWinds APE, the installer errors with "Operating system: Windows Server 2025 does not meet the system requirements for SolarWinds Platform."
We know this is incorrect as the SolarWinds Platform requirements states Windows Server 2025 is supported. Here's what our team determined…
We were able to find a workaround for this issue.
This is still an issue with the latest installer not properly developed for backwards compatibility.
Though the error claims to be Windows Server 2025 isn't supported, which we know is a false statement and should be removed from the installer completely, the issue was the main polling engine version mismatch with the latest installer's version.
Our main polling engine is on version 2026.2.1
The latest installer is version 2026.2.2
If a newer version of the installer was run already, then an older version of the installer must be run before installing the version that matches the main polling engine.
In this case, I tried to install Solarwinds-OOAE-2026.2.2-OfflineInstaller, which errored.
When attempting to install the version that matches our main polling engine, Solarwinds-OOAE-2026.2.1-OfflineInstaller, it errored with the same Windows Server 2025 not supported error.
This is what fixed that specific scenario...
- Run the
Solarwinds-OOAE-2026.2.0-OfflineInstaller - There will be a version mismatch error preventing from going further
- Cancel the installation once the error occurs
- Run the
Solarwinds-OOAE-2026.2.1-OfflineInstaller - The Windows Server 2025 unsupported error is no longer present
- Continue with the installation
- Follow the configuration wizard
If a newer version of the installer wasn't run already, then running the installer equivalent to the main polling engine's version works fine.
Meaning on a server we hadn't run any installers on, the Solarwinds-OOAE-2026.2.1-OfflineInstaller worked without error.
This must be something to do with the installer's cache, lack of backwards compatibility, and improper error detection.
