Cannot load printer software for HP Photosmart C7250, always get fatal error and software does not install hp solution center , digital imaging monitor or photosamrt essentials

Try to use another installation disk.your disk might got a problem..

Uninstall again, George. Correct approach this time.

In Add/Remove Programs uninstall anything, associated with the HP PhotoSmart C7250 All-In-One Printer.

If it asks you to restart your computer -> NO.

Close all windows, go back to your desktop screen. Turn the computer off normally.
UNPLUG the computer from power, AT the surge protector, NOT at the back of the Power Supply)

Now get that printer unplugged from the computer. (Printer off. Then unplug printer from power)

Press the Power On button in, and hold it in for a count of 10 seconds. (And I mean at least 10. Count)
Let go of the Power On button.
Do this same procedure two more times.

What you are doing is clearing CMOS Error Codes, and resetting BIOS Setup back to the factory default settings.

Plug the computer back into power. WAIT 1 minute, turn the computer on.
Load the software.

NOTE*
Before loading look at the software disk at an angle.
Do you see scratches, dust/dirt, etc? If dust/dirt, wipe the disk off properly.
Use a cloth designed for cleaning CD disks. WIPE across from the inside edge to the outside edge. Yes, several places until the entire disk is clean.
Do NOT go round, and round on the disk.

If scratched set the disk aside. I will give you the link to the software on HP Support. Download AND install it. Do not know how? Hit me up in a Comment, I'll guide you.

Windows running, software loaded?
Go to the All-In-One. Open it as you would to replace the cartridges.
Now close it. Now plug it into power.
Wait until you hear it reset itself. (Cartridge carrier goes across, then back to home. Printer performs checks, then ON, LED light is lit)

Now plug the printer's USB cable into the computer. Wait a few seconds.
You should get a pop-up out of the system tray, at the bottom of your monitor screen, "New Hardware Found"
Then another one, "Found Photosmart ya-da, ya-da"

You didn't have the drivers installed BEFORE you plugged the printer in.

Drivers: Small pieces of software that allow the Operating System to communicate with a device.

Some O/S examples; Windows XP, Windows Vista, Windows 7.
Device in this case is that printer.

When a new device is installed Windows 'breaks it's neck', to find suitable, matching drivers. If THE drivers are not there, Windows will match up one of it's THOUSANDS of generic, one size fits all, drivers.
This = No.

When a printer is installed on a computer, it is -> Imperative that the drivers are installed F-I-R-S-T, then the printer. USE INSTALLATION DISK first, should be all over the printer, and the Quick Guide.

In fact, don't even scr3w with the Installation Disk again. Let's use the software provided by HP Support,
