HomeGuides :: Attach PlusTroubleshooting Tips and TricksPrinter not activated, error code -20

9.33. Printer not activated, error code -20


When the user attempts to install, they receive an error dialog stating "Printer not activated, error code -20"


This is almost always a permissions-type issue where 1) UAC is disabled and preventing the user from seeing the elevation dialog, or 2) the user doesn't have permissions to install properly.


Note:  The user installing Attach Plus needs to be an administrator on the PC.

First ensure that you have UAC set as we recommend here:  User Account Control (UAC) Information.  Once UAC is properly set (often requires a reboot), then re-run the Attach Plus installer package.  If that doesn't resolve the issue, follow these steps to get it properly installed:

  1. Close Attach Plus
  2. Navigate to Attach Plus installer package
  3. Right-click on the installer package > Run as Administrator
  4. Allow Attach Plus to install and then launch
  5. Close Attach Plus (This step is important!!)
  6. Re-launch Attach Plus normally (do NOT run as administrator this time)
