What changed in 1.5.1 · Interactive stamp guide · All guides

Update to 1.5.1

  • Save your work. On Mac, choose Help > Check for Updates and follow the prompt. On Windows, the update downloads in the background and installs when you quit.
  • After relaunch, About should show version 1.5.1, build 23. Your existing PolyPDF 1.x Pro license continues to apply.
  • If an update is unavailable, use the current Mac or Windows download on this site. Mac requires macOS 14 or later on Apple silicon or Intel; Windows requires Windows 10 or 11, x64.

Stamps, presentation, and metric dimensions

  • Open the arrow beside Stamp > Create Interactive Stamp… to start with a blank canvas. Add to toolset is optional and unchecked by default.
  • For a placed interactive stamp, use Properties to change its values. A visual stamp does not create a certificate signature.
  • Open a PDF and choose View > Presentation Mode. Use arrow keys to change pages and Escape to return to the workspace.
  • New metric dimensions default to millimetres. Existing document formats are preserved; check Measurements > Formatting and verify the page scale when a displayed value is unexpected.

Revision Package help

  • For a Revision Package issue, include the stage you were in: import, reconciliation, changes and impact, references, or publication.
  • Include the issue label, affected sheet number, and the exact message shown. Do not email confidential drawings unless support asks for a safe reproduction.
  • Free users can view and navigate an existing Revision Package. Creating or changing package state and publishing require PolyPDF Pro.

Activating your license key

  1. Check your email for the key. It is sent as soon as Stripe confirms the payment and looks like PPM-XXXX-XXXX-XXXX.
  2. Open the upgrade window in PolyPDF.On a Mac: PolyPDF ▸ Upgrade to PolyPDF Pro… ⌘⇧LOn Windows: Help ▸ Upgrade to PolyPDF Pro… Ctrl+⇧+L
  3. Paste the key and click Activate. No restart, no reinstall. The measurement cap lifts and Symbol Search plus plugins unlock as soon as the key is accepted. The drawing you had open keeps every measurement and markup already on it.

Your license key is emailed the moment Stripe confirms payment — normally it arrives within a minute. If it has not shown up in 15 minutes, check spam, then email support@polypdf.com.

One license activates up to 3 computers, Mac or Windows in any mix. Moving to a new machine when all 3 are used? Deactivate on the old one from the same window, then activate on the new one.

Before you contact support

  • Confirm you are running the version you downloaded from PolyPDF.com.
  • Include the app version and build number if you can.
