1. Purpose

Puts the tool into the exact Revit build in use with one installer run, instead of hand-copying files into the add-ins folder. A one-time job — later releases just install over the top to upgrade.

3. Steps

Close Revit fully, then run the per-user installer (VP_RevitAPI-<version>-SingleUser.msi) — it needs no admin rights. [image 01: the downloaded installer file]
On the welcome screen click Next; in the feature tree tick the Revit version(s) in use (2024, 2025...), then Install. There is no destination-folder choice — Revit only reads its own per-year add-ins folder, so the installer puts everything in the right place itself. [image 02: feature tree with the Revit year ticked]
When done, reopen Revit: the VP_MEP, VP_LAYOUT, and VP_Manage tabs on the ribbon mean success. [image 03: the 3 tabs on the ribbon after install]

4. Real-world example

A fresh machine with Revit 2025 for plumbing work. Close Revit, run VP_RevitAPI-1.4.0-SingleUser.msi, tick only 2025, Install — reopen Revit and the VP_LAYOUT tab is there, ready to put views in sheet. Under five minutes, start to finish.

5. Common errors

Symptom	Fix
Reopened Revit shows none of the 3 tabs	The installer wrote to the wrong Revit year — rerun it and tick the exact Revit year in use
Old version still sits next to the new	Builds with different upgrade codes install side by side — uninstall the old one in Control Panel, then reinstall the latest
Install fails halfway	Revit is locking files — close Revit fully (check Task Manager for leftover Revit processes), then reinstall
