WinFSP is showing an "Already Installed Error"

The "WinFsp is already installed" or "newer version installed" errors were likely caused by residual files, registry entries, or a versioning conflict from a previous WinFsp installation. You can resolve this issue by downloading the newest version of WinFSP at https://github.com/winfsp/winfsp/releases/tag/v2.1B2.

This version resolves the issue by properly cleaning up older versions of WinFSP on your machine.
