Scan Function Lost After Windows 10 Upgrade

[lindanz]

I'm now having an issue with hubby's, the message coming up when I'm doing the L4 uninstall 

HP Installer Uninstaller has stopped working

**** Now fixed****

Hi JohnGPB,

Let me just say, "YOU ARE A LEGEND".

I have wasted so much time on this problem and after following your post my scanner finally works correctly from HP Solution Centre. I upgraded from Win7 to Win10.

Thank you so much for saving my sanity. I was literally very close to throwing my OfficeJet 8500 Pro out the window.

Just one question for HP:

Having a background in Win programming I can appreciate the install etc is no simple matter. However with all the complaints and utterly frustrated people (with many more outside this forum) WHY did you at least not post something and say you were working on a solution to the problem? That assumes of course, you were... Loyal customers cost you VERY LITTLE, but loyalty greatly enhances your bottom line. Whether you eventually find this is an HP specific problem or not, a little care goes a very long way. At LEAST tell people you are listening! End rant.

Hey @JohnGPD, thanks for the walk-thru. Unfortunately, I got all the way to step 13 and now I have a seemingly worse problem. During install, I now get a fatal error "Could not open key: UNKNOWN\Components\CEEAC1BBA7EAD113A1A0030399AF16C\6E3C12FFDF79F4745981D8BC9EC48245"

Any words of wisdom to overcome this other than replacing my 8500 with a POS Canon?

Thanks in advance!

@xxTap.

Hey there,

This error means that you are having insufficient priviliges on your computer..

If you are an Administrator try the following steps, if not, log into an administrator account and try again.

Open up the registry editor by pressing on Win-key + R >> in the run windows type in "regedit"

Inside the registry editor, head into: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet and Right click on the "Enum" folder in here, and choose the "Permissions" option.

In here Press on "Add" another window will open, in it type in "Everyone" and press "Check names" and press OK.

It will lead you back to window we had before, here Mark "Everyone" and give it full control, Press "OK" afterwards.

And just try to install again.

If its not letting you apply the changes to "Everyone" then that means that something in the way your OS Was installed went wrong, and somehow your User account dosen't have sufficient privliges.

Best of luck~

@JohnGPD

Spot on advice! I couldn't change the permissions for the Enum key, which led me checking if I could change the permissions for 6E3C12FFDF79F4745981D8BC9EC48245 and found that the uninstall process removed the owner. Once I set my account as the owner of that sub-key and re-ran the install, another key with 6E3C12FFDF79F4745981D8BC9EC48245 as a sub threw an error.  I then search the entire registry for 6E3C12FFDF79F4745981D8BC9EC48245 sub-keys and found 12 or so that did not have an owner.  Once I took ownership of all of them, the install completed without an error.

I CAN SCAN AGAIN!!!

thank you very much!!

Please confirm that the installation in Step 13 should be completed by using the file downloaded in step 2.

I have tried the process outlined twice now.  Although, my first go, I did get through most of the steps before I connected that since I am on an HP that many of the steps were not required.  Did I mess up my solution result by doing this?

Here is the message that I got after both times goinf through the steps:

Also, both times that I ran the "Uninstall_L4", I received this error:

[lindanz]

Make sure you are doing it as Administrator and don't stop anything or miss any steps.

Yes, I have administrator priviledges.  I retraced the steps exactly for having an HP computer (alternate Step 4 and omitting Steps 5-8 and 11).  I still get the same scanner error message as before towards the end of the install nd again when the system reboots.

Should I be following the steps as a non-HP computer user?
