Windows 10/11 · per-user install · no admin rights

Download

Three downloads: the Revit add-ins in one installer, Parapet Desktop and Parapet Scan. The installer detects the Revit releases on your PC and installs for those only. Nothing touches your models.

Parapet for Revit 2020-2027

Hub, Link and Audit in one installer - Audit is free, Hub and Link have 14-day trials, and one Parapet Pro key unlocks everything. Windows 10/11, per-user, no admin rights.

Parapet Desktop

Audits .rvt, .rfa and .rte files without opening Revit. The free edition is the whole audit and needs no registration. Windows 10/11, 64-bit, with the .NET 9 Desktop Runtime.

Parapet Scan

Compares laser scans with the model, element by element. The app is free. Take the Revit package if the point cloud is already placed in your Revit model; the app package carries both.

Your browser or Windows warned about the download

Chrome and Windows SmartScreen warn about installers they have not seen many times before. It is a warning about how new the file is, not about anything found in it. Parapet installs into your own user folder, needs no admin rights and never writes to your models.

Chrome - open Downloads (Ctrl+J), find Parapet-Setup.exe and choose Keep. Windows - if a blue SmartScreen panel appears, click More info then Run anyway. The same applies the first time you start Parapet Desktop or Parapet Scan: their files are not code-signed yet.

Prefer to skip the installer? The portable ZIP is the same files, copied by hand.

Check you got the real file: run certutil -hashfile Parapet-Setup.exe SHA256 and compare it with the published SHA-256. The list covers every file on this page.

Portable ZIP - no installer

Same files as the installer. Pick your Revit year, unzip it, and copy both items from the <year> folder - Parapet.Hub.addin and the ParapetHub\ folder - into %AppData%\Autodesk\Revit\Addins\<year>\. Repeat per Revit year.

Windows marks files from the internet as blocked, and Revit will then load nothing at all: right-click the ZIP → Properties → tick Unblock before you unzip it. Checksums: SHA256SUMS.txt.

What a key unlocks

The Revit installer contains Hub, Link and Audit; Parapet Desktop and Parapet Scan are their own downloads. Which apps are unlocked depends on your licence, not on what you download, and one Parapet Pro key unlocks them all.

One installer. A Parapet tab with Hub, Link, Audit and Licenses in every Revit you run.

Install in 3 steps

Close Revit, run the installer, tick the Revit versions you want (detected ones are pre-selected).
Start Revit. A Parapet tab appears in the ribbon.
Click License → Start free trial or paste your key → Activate. Free apps skip this entirely.

Where it goes

Per Revit year: %AppData%\Autodesk\Revit\Addins\<year>\Parapet.Hub.addin plus a ParapetHub\ folder. Uninstall from Windows Settings → Apps.

Parapet Desktop in 3 steps

Install the .NET 9 Desktop Runtime (x64) once, if Windows asks for it.
Unblock, then extract. Right-click the ZIP → Properties → tick Unblock, then extract all of it to a folder of your choice, for example %LocalAppData%\Programs\ParapetDesktop.
Run ParapetDesktop.exe and drop a model on the window. Pro is activated on the Pro page at the bottom of the sidebar.

To remove it, delete the folder. Your scan library and settings live in %LocalAppData%\ParapetDesktop.

Parapet Scan in 3 steps

Install the .NET 10 Desktop Runtime (x64) once. A computer with Revit 2027 usually has it already.
The app: unblock the ZIP, extract all of it and run ParapetScan.exe. For the Revit add-in, right-click install-revit-addin.ps1 in the same folder → Run with PowerShell.
The Revit package alone: unblock the ZIP, extract it and copy the ParapetScan.Revit.bundle folder into %AppData%\Autodesk\ApplicationPlugins\, then start Revit: Parapet tab → Scan.

Reading .rcp and .rcs scan files needs Revit 2027 on the same computer. Point clouds placed in a Revit model are read through Revit itself, in any release from 2021.
