unable to un-install HP 8620 Software

Hi Experts,

I installed the full package of an HP 8620 PRINTER/SCANNER and it won't print or scan anymore. I was trying to un-install it so that I can re-install it but I can't I got these messages below.

failed to read ini file :\programdata\hp\hp officejet pro8620\ (and a bunch of numbers) ini

call the driverpackage install returned error -536870141 for package c:\progam files\hp\hp officejet pro\8620\driver source\NG ScanDriver\HPWia_OJ8620

Please help

John

Open Devices and Printers, click once (only) any printer to open the Printer Server Properties menu. Go to Drivers and delete the HP8620 driver and the fax driver. Close out, shut down, start up and try installing the printer again.

If it installs but does not connect, go to Programs and Features, select the printer and run a Repair.

These two steps normally work. I have an HP 8610.

If using Windows 10, make sure you have the latest driver (OJ8620_198.exe)

I suspect you have tried John's suggestion, which is why you get an error about the ini file. If I'm correct, try hacking the printer from the registry. Go to

HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > Print > Environments > Windows NT x86 > Drivers > Version-3

Right-click the printer in the left pane and delete it. If you have a 64-bit system, also delete it from

HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > Print > Environments > Windows x64 > Drivers > Version-3

Now stop and restart the spooler and reinstall the printer.

If this is a network printer (connected via a server), go to

HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > Print> Providers > LanMan Print Services > Servers > Printers and to
HKEY_CURRENT_USER > Printers > Connections
and delete the printer from there

hi guys, same results. I tried both recommendations and i'm not getting anywhere.

John

There are a number of bits that go with that printer: Basic Software, Help, HP Update and I.R.I.S OCR that are in Programs and Features. Can you uninstall everything there?

there is nothing else installed except the HP Printer software.

John

Go to Programs and Features, locate the printer software, click on Repair and repair the software. That will require a restart so close all applications first
