Peter, can you check this filepath and see if the folder is listed on your
computer?

C:\Windows\System32\DriverStore\FileRepository\prn hp001.inf_5641fa75 The
last digits may be different. The prnhp001.inf_ bit is the important part.
The folder should be approximately 67MB in size. It contains the inf and
drivers for the HP printers. And yes, yours is listed.

Many thanks for your advice.

But because Vista has the HP drivers built in, HP do not have them available
on their web pages for down load.

Your problem is the same as ours here: http://tinyurl.com/2ml2eb

The solutions you have been given here will not work as it is a more
deep-rooted problem IMHO.

Gav

I had the same "Core Program" problem with an HP Deskjet 845c.

After investigating a bit I've learned about the Printer drivers in Windows Vista, and what they call now "Package Aware Drivers" and "Core drivers".

What the HP driver was saying to you was that it couldn't find a "Core Driver" in your system. After taking a look at the HP .inf file "C:\Windows\System32\DriverStore\FileRepository\pr nhp001.inf_5641fa75\prnhp001.Inf" and found the "Core Drivers" required are UNIDRV and sRGBPROFILE.OEM.

I also had a look at the MS printer .inf "ntprint.inf" and discovered that sRGBPROFILE.OEM (and UNIDRV, and the other "Core Drivers") is described there, but it's not copying any file.

I found in the registry there where two entries for two "Core Driver" GUIDS finishing in ...F0 and ...F5 (UNIDRV and XPSDRV), they are located in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\PackageInstallation\Window s NT x86\CorePrinterDrivers.

So here comes the solution/cheat...

I exported the registry key for one of the "Core Drivers" and modified it to create one for the sRGBPROFILE.OEM GUID ({D20EA372-DD35-4950-9ED8-A6335AFE79F3}), then imported this file into the registry, and voila.... Now my printer is working:

This is the content of the .reg file:

_______________________________________

"InfPath"="C:\\Windows\\System32\\DriverStore\\Fil eRepository\\ntprint.inf_a6d3ccdf\\ntprint.inf"
"DriverDate"="06/21/2006"

I hope this solves your problem....

Sorry, there was a problem with the .reg I included, this is the good one.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\PackageInstallation\Window s NT x86\CorePrinterDrivers\{D20EA372-DD35-4950-9ED8-A6335AFE79F3}]

Here is the fix for the "Empty Printer List".

C:\windows\inf\INFCACHE.1 is most likely corrupt and should be deleted.
You will need to edit its file permissions to give Full Control to the
User Group before you will be allowed to delete it.

I personally used this method and it works and works well. But I assume no liability or credit.

WOW,

This solution worked for me. I spent 1 1/2 hours with Hp tech support and 20 minutes with Microsoft Vista tech support and neither one could help me. After I moved the infcache.1 to another folder I ran the add printer wizard and I was able to see my printer (Hp Photosmart 3310 All-in-one) and it detected it, I set it up on the USB port and printed a test page, then I went into device manager under other and clicked to update driver and it recognized the printer and completed installing the rest of the Hp software.

Thank you very much

Hi, I recently upgraded to Windows Vista and everything was great! However a
few weeks go by and all of a sudden, my video card driver is gone. I am
using an older card, so no Aero for me, nVidia GeForce 4000. When I
installed Vista, the drivers were there, WDDM drivers were installed. nVidia
does not make the drivers for it and now I am stuck using the basic Standard
VGA Adapter driver. Please help, this is my mom's PC.

I suspect the drivers that were there were carried over in the upgrade from
XP to Vista. It's possible the system discovered a compatiblity or
stability issue and possibly removed those drivers. Even if you could find
the drivers and reinstall, I suspect this will continue to be an issue.
Your best bet would be to replace the video card. There are plenty of
inexpensive cards around. Just be sure you check the manufacturer's website
before you buy to be sure of availability of Vista compatible drivers.

I'd also point out, nVidia is still having a lot of trouble with their
drivers. You might want to consider an ATI card. With the exception of
some of their better cards, the 1900 series and all in wonder series cards,
they seem to have had pretty good luck with their drivers thus far.
