Everything you need to install, activate and get the most out of Parapet apps. Email support if anything is unclear.

1. Install

Close all Revit windows.
Run Parapet-Setup.exe from the download page - one installer for all three apps. It lists Revit 2020-2027 and pre-selects the versions found on your PC.
Start Revit. The Parapet tab appears with Hub, Link, Audit and Licenses.

Installers are per-user (no admin rights) and write to %AppData%\Autodesk\Revit\Addins\<year>\. If Revit shows the Security - Unsigned Add-In dialog the first time, choose Always Load.

Manual install (portable ZIP)

Unzip. For each Revit year you use, copy <year>\Parapet.Hub.addin and the <year>\ParapetHub\ folder into %AppData%\Autodesk\Revit\Addins\<year>\.

2. Activate

Click Parapet → Licenses and pick the app (Hub, Link). Audit is free and needs nothing.

Free apps register silently - no key, no trial, nothing to do.
Free trial (Pro apps): click Start free trial. 30 days, full product, one trial per computer.
Subscription: paste your key (e.g. PH-XXXXX-XXXXX-XXXXX-XXXXX) and click Activate. One key works on 2 computers and on every Revit version.

The add-in checks in with the license server in the background about every 12 hours and runs offline for up to 14 days between check-ins. To move to another PC use Deactivate this computer in the dialog, or the account page.

3. Using the apps

Hub opens the element window; Link the spreadsheet window; Audit the CAD list.
Select elements in the category → family → type tree. Selections persist while you switch categories.
Review parameters in the grid; choose columns with Select parameters; edit cells to write values back.
Run actions from the right-hand cards. Cards with inputs validate before running and show their result inline.
Link data: in Excel Manager choose Excel, CSV or Google Sheets, preview the source, map columns, validate, push.

4. Licensing FAQ

"License needs to be re-validated online"

Your 14-day offline window passed. Connect to the internet and open the app again - it refreshes automatically. If your network filters traffic, allow this site's domain on port 443.

"This license is already active on 2 computers"

Free a seat from the account page → Deactivate, then activate again.

"The free trial has already been used on this computer"

Trials are one per computer. Subscribe to continue - or contact support if you believe this is a mistake.

Payment failed / "payment overdue"

Stripe retries automatically and the app keeps working for a short grace period. Update your card from the account page → Manage billing.

Does Parapet send my model data anywhere?

No. The only traffic to us is the license check: key, a hashed computer id, computer/user name, Revit and add-in version. If you link a Google Sheet, that data moves between your computer and Google under your own account. See Privacy.

5. Troubleshooting

Which build loads where - the usual cause of a missing Parapet tab.

No Parapet tab: confirm %AppData%\Autodesk\Revit\Addins\<year>\Parapet.Hub.addin exists and the ParapetHub\ folder is next to it. Re-run the installer.
Revit 2025-2027 can't load the add-in: update Revit; these versions require the .NET 8 runtime that Revit ships.
Conflicts with other add-ins: Parapet Hub ships its own ClosedXML, Google Sheets API and Newtonsoft.Json inside its folder. If another add-in loads an older copy first, Excel/Sheets linking may fail - tell us.
Proxy / firewall: system proxy, TLS 1.2, port 443.

6. Uninstall

Windows Settings → Apps → the Parapet app → Uninstall. Your license stays valid; deactivate the computer first to free the seat.

7. Checksums
