An implementation of Visual Basic that is built into Microsoft products.
The “Run-time error ‘53’ – File not found” message when opening Word is caused by Visual Basic for Applications (VBA) trying to load a file (often from an add‑in) that no longer exists at the specified path.
In current Word installations, this is frequently triggered by a third‑party add‑in, most commonly from Adobe (Acrobat/PDF add‑ins) that left behind an invalid reference. The add‑in tells Word/VBA to load a DLL or framework file, but that file has been moved or removed, so VBA raises error 53.
To resolve this kind of problem:
- Identify and remove or update the problematic add‑in (for example, an Adobe/Acrobat PDF add‑in) so that Word no longer tries to load the missing file.
- If the error is caused by Adobe’s components, follow Adobe’s guidance or contact Adobe/Acrobat support, as they control the add‑in and its file locations.
- If Word or Office itself appears damaged (for example, other VBA features fail), run an Online Repair of Office to restore missing or corrupted components.
If the error text includes a path under an Adobe or Acrobat folder, the fix must come from removing or correcting that Adobe add‑in.
