HP Support Assistant - Unsuccessful Network Installation

[LakeGator]

I have a HP OfficeJet Pro 8135e printer.  I am afflicted by Windows 11. I have, apparently, misconfigured my system in trying to eliminate the annoying and bogus popup informing me that scan to computer has failed.  I was always able to scan to and from the computer until I followed the instructions to eliminate the bogus popup message.  The instructions entailed removing all instances of the printer and scanner from the computer and reinstalling.

I did get the printer installed and working but my attempts at connecting the scanner using HP Support Assistant have failed.  When I select wireless option and click Next, I am shown the scanner with the correct IP address and MAC address.  Selecting that device and clicking Next results in “Unsuccessful Network Installation” with no clues provided about the actual error.  Both the computer and scanner are on the same 5G Wi-Fi network.

I can scan using HP Smart but HP Scan fails.

I would appreciate any guidance about how to get the scanner back in full access.

Thanks!

Hi @LakeGator 

Welcome to the HP Support Community! We're here to help you get back up and running.

Thank you for laying out the details so clearly. Let’s go step by step to restore full scanning functionality on your HP OfficeJet Pro 8135e with Windows 11:

Step 1: Confirm Printer and Scanner Drivers

1. Open Control Panel > Programs and Features.
2. Remove any duplicate or partial HP printer/scanner software entries.
3. Restart the computer.
4. Reinstall the full feature software package for your printer (this ensures both print and scan drivers are correctly installed).

Step 2: Verify Windows Services

1. Press Windows + R, type services.msc, and press Enter.
2. Locate and ensure the following services are running and set to Automatic:
   • Windows Image Acquisition (WIA)
   • Remote Procedure Call (RPC)
   • DCOM Server Process Launcher
3. If any are stopped, right-click and select Start.

Step 3: Check Network Configuration

1. Ensure both the printer and computer are connected to the same Wi-Fi band (5 GHz or 2.4 GHz). Some scanning functions work more reliably on 2.4 GHz.
2. Print a Network Configuration Page from the printer’s control panel and confirm the IP address.
3. On the computer, open Command Prompt and type ping <printer IP> to verify connectivity.

Step 4: Add Scanner Manually

1. Open Control Panel > Devices and Printers.
2. Select Add a device and wait for the scanner to appear.
3. If not detected, choose The printer I want isn’t listed > Add a printer using TCP/IP address.
4. Enter the printer’s IP address and complete the setup.

Step 5: Test with HP App

1. Open the HP App and confirm scanning works there.
2. If HP App scans successfully but HP Scan fails, uninstall HP Scan and reinstall it from the full feature package.

Step 6: Reset HP Scan Settings

1. Navigate to C:\ProgramData\HP\HP Scan.
2. Rename the folder to HP Scan.old.
3. Restart the computer and launch HP Scan again. A fresh configuration will be created.

Step 7: Firewall and Security Software

1. Temporarily disable any third-party firewall or antivirus software.
2. Test scanning again.
3. If successful, add exceptions for HP printer/scanner services in your security software.

By following these steps carefully, you should be able to restore full access to scanning from both HP App and HP Scan.

Thanks very much for your informative and effective reply.  My printer now scanning and well as spraying ink on almost innocent paper.

Unfortunately, the very annoying popup notifications from ScanToPCActivationApp every few seconds informing me (apparently in error) that Scan to Computer is not working. 

I finally gave up and went to the System > Notifications settings and turned off the notification from that rather chatty piece of software.  I hate doing that in case this thing will ever want to alert me to something that is actually true and possibly important.

Thanks again!

You are very welcome @LakeGator 

It sounds like you’ve done a thorough job of getting the printer and scanner back online, but that persistent ScanToPCActivationApp popup is the last piece of the puzzle. 

Here are a few ways you can tame it without losing useful alerts:

 

Options to Manage ScanToPCActivationApp

Disable “Scan to Computer” in HP Utility
Open the HP Printer Assistant (part of the full feature software).
Go to Scan > Manage Scan to Computer.
Uncheck Enable Scan to Computer.
This stops the background service that generates the popup, but you can still scan from the computer using HP Smart or HP Scan.

Control Startup Behavior
Press Ctrl + Shift + Esc to open Task Manager.
Go to the Startup tab.
If you see ScanToPCActivationApp, set it to Disabled.
This prevents it from auto-launching at boot, so you won’t get repeated notifications.

Selective Notifications
Instead of turning off all notifications for the app, you can go to Settings > System > Notifications > HP and fine‑tune which alerts are allowed. That way, you suppress the “Scan to Computer not working” spam but keep critical alerts.

Fallback Approach
If you ever need “Scan to Computer” again, you can re‑enable it in HP Printer Assistant with one click. It doesn’t affect scanning from HP Smart or HP Scan.

You’ve already proven the scanner works fine through HP Smart, so disabling or controlling ScanToPCActivationApp won’t take away any functionality—it just silences the noise.
