Manual service start fails
Example event log error
Root cause
Application security solutions may prevent running a .NET runtime version with known vulnerabilities. (e.g. Microsoft Defender Vulnerability )
MFT installation also installs a .NET runtime version that services will try to use. If this version has since been discovered to have vulnerabilities, services will try to use a patched version if installed. When the patched version is also not available, the Next service will fail to start.
Resolution
Install the version mentioned in the event log, or the latest available .NET 8 version for
- .NET Runtime
- ASP.NET Core Runtime
