Can no longer connect to my printer due to Windows error C0000022 ... This error states there is a conflict with 2 exe files preventing connection and I am unable to install HP Smart App or printer driver needed for this connection.

Hi @cindy7777,

Welcome to the HP Support Community.

Thank you for sharing the details about your HP DeskJet 2742e All-in-One Printer. I understand how frustrating it can be when Windows shows error C0000022 and prevents you from installing the required HP software or connecting to your printer.
 

Please note that the latest setup application for HP printers is the HP app. Since the error is stopping the installation, please try the following basic troubleshooting steps:
 

1. Restart the printer and computer

  1. Turn off the printer.
  2. Disconnect the printer power cable.
  3. Restart the computer.
  4. Wait until Windows fully loads.
  5. Reconnect the printer power cable and turn it on.
  6. Try installing the HP app again.
     

2. Run Windows Update

  1. Press Windows + I to open Settings.
  2. Select Windows Update.
  3. Click Check for updates.
  4. Install any available updates.
  5. Restart the computer and try installing the HP app again.
     

3. Remove previous HP printer software

  1. Press Windows + R.
  2. Type appwiz.cpl and press Enter.
  3. Look for any HP printer software.
  4. Uninstall any HP-related printer software available.
  5. Restart the computer.
     

4. Remove the printer from Windows

  1. Press Windows + I to open Settings.
  2. Select Bluetooth & devices.
  3. Select Printers & scanners.
  4. Select your HP DeskJet 2742e printer.
  5. Click Remove.

Restart the computer after removing the printer.
 

5. Install the HP app and set up the printer

  1. Install the HP app.
  2. Open the HP app.
  3. Follow the on-screen instructions to add your HP DeskJet 2742e printer.
  4. Complete the printer setup.
     

If the C0000022 error continues, please provide:

  • Your Windows version (Windows 10 or Windows 11).
  • When the error appears (during HP app installation, driver installation, or printer connection).
  • Whether the printer is connected through Wi-Fi or USB.
  • A screenshot or the exact error message.

With these details, we can assist further with getting your HP DeskJet 2742e connected and working again.

I'm an HP Employee.
