It looks like you’re referencing a patch, crack, or keygen for Autodesk 2014 products (likely AutoCAD, Revit, or similar), specifically for 64-bit systems — with “Xf Adsk2014” being a well-known activator from the XF keygen team.
What it usually is
Common interpretation: A redistributable/patch or component bundle related to Autodesk 2014 (e.g., AutoCAD, Revit, 3ds Max) for 64-bit Windows. The name suggests an Autodesk (Adsk) release tied to 2014 and a 64-bit architecture.
Typical contents: Installer wrappers, licensing components, runtime libraries (Visual C++ redistributables, .NET packs), or small update utilities Autodesk includes with product installs or service packs.

Security and source advice
Only use Autodesk or your organization’s official downloads. Avoid unknown “cracked” or repackaged installers—these pose malware and legal risks.
Keep backups of installers and license information for legacy software you must maintain.
