    To run tscdiag from any location:

    Note: You must have administrative privileges to properly run diagnostics, as the tool queries system services and security event logs.

    No official Microsoft tool named "TSC Diagnostic Tool v1.64" is listed in current Microsoft Download Center catalogs.
    However:

    The TSC Diagnostic Tool v1.64 remains a quiet hero for IT professionals maintaining legacy RDP environments. Its lightweight design, detailed reporting, and no-nonsense command-line interface can save hours of tedious troubleshooting.

    To download safely:

    Remember: while the tool tells you what is broken, it does not fix it for you. Pair it with a good understanding of Remote Desktop Services permissions, Group Policy, and Windows Firewall rules to become a true RDP troubleshooting expert.

    Last tip: Always test the tool in a non-production environment first. Keep a backup copy of tscdiag.exe on your admin USB drive – you never know when a legacy server will need it.
