Pre-requisites for installing SilhouetteConnect on Windows 11

SQL Server Issues on Windows 11

SilhouetteConnect uses Microsoft SQL Server, which can have can have issues running on Windows 11 when the disk sector size is greater than 4 KB. In this case the installation of SQL Server may fail, or the Database Engine Service will not be able to start due to the unsupported file system. This can occur for both SQL Server Express (SilhouetteConnect Standalone mode) and LocalDB (SilhouetteConnect Synced mode). This issue is only likely to occur if using an NVMe drive.

You can confirm whether you may encounter this specific issue by:

1. Running the command from an administrator command prompt: fsutil fsinfo sectorinfo C:

2. Look for the value PhysicalBytesPerSectorForAtomicity, returned in bytes. A value of 4096 indicates a sector storage size of 4 KB.

3. If PhysicalBytesPerSectorForAtomicity is showing a value other than 4096 then you will need to apply one of the resolutions in the Microsoft troubleshooting article https://docs.microsoft.com/en-us/troubleshoot/sql/admin/troubleshoot-os-4kb-disk-sector-size prior to installing SilhouetteConnect.

If you have already installed SilhouetteConnect before encountering this issue then you may need to uninstall SQL Server before applying a fix.
