Solution for Installation Error for HP Devices – Windows Vista
We have detected that you were unable to successfully complete the installation for your HP device. All of the files that we attempted to install have been removed. Follow the procedures in this document to install your HP device after receiving an installation error.

Note	Please make sure you have turned off and restarted your PC before trying the steps outlined below.	

Step 1: Run the Disk Cleanup utility 
The software installation process uses certain system folders for preparing files for installation. Periodically, these folders need to be cleared. Prior to installing again, run the Disk Cleanup utility, which will help you:
·	Delete temporary Internet files
·	Delete downloaded program files
·	Empty the Recycle Bin
·	Delete files from the temporary folder
·	Delete files created by other Windows tools
·	Remove unused, optional Windows components
To use the Disk Cleanup utility:
1.	Click Start ( ), click All Programs, click Accessories, click System Tools, and then click Disk Cleanup. 
2.	After the Disk Cleanup utility analyzes the hard drive, a report with a list of options appears on the computer. Click the appropriate check boxes to remove unwanted files from the computer, and then click OK. 
3.	Click Yes on the confirmation screen that appears on the computer. 

Step 2: Reinstall HP Software
Note	Before starting the installation process again, please confirm the following:
·	Unplug the USB cable from the device (if you are connecting to the printer via USB cable). 
·	Make sure your PC has been rebooted at least once since the failed installation.  	
Reinstall the HP software by re-inserting the CD that came with your device. 
Please follow the onscreen instructions, and connect the USB cable only when prompted by the software. The illustration below shows a typical USB connection.

Note	If the USB cable is connected to a USB hub or a docking station for a laptop, it could cause the installation to fail. Try connecting the USB cable directly to the computer during the device installation (when prompted).	

Step 3: Temporarily Disable Startup Software
If you were again unable to successfully install your HP device, you may need to temporarily disable startup software. Windows allows many programs and processes to run immediately upon startup. These programs may be preventing you from installing the HP Software. These directions explain how to temporarily disable these programs and processes while installing the HP device. (Step 5 below will explain how to re-enable the startup software.)
1.	Click the Windows icon on the Windows task bar ( ), type msconfig in the Start Search text field, and then press Enter. 
2.	The System Configuration Utility appears. If the radio button next to Normal startup is currently selected, follow the steps under Normal Startup.  If the startup option is set to Selective, follow the steps under Selective Startup.

Note	After completing Step 4 below, don't forget to restore the startup software that you temporarily disabled. (Step 5 gives you the instructions for restoring the startup software.)  Without restoring your startup software, your PC may not function the way that you expect.	

Step 4: Reinstall HP Software
Note	Before starting the installation process again, please confirm the following:
·	Unplug the USB cable from the device (if you are connecting to the printer via USB cable). 
·	Make sure your PC has been rebooted at least once since the most-recent failed installation.  	
Reinstall the HP software by re-inserting the CD that came with your device. 
Please follow the onscreen instructions, and connect the USB cable only when prompted by the software. The illustration below shows a typical USB connection.

Step 5: Re-enable Startup Software

1.	Click the Windows icon on the Windows task bar ( ) and then type msconfig in the Start Search field .and then press Enter. The System Configuration Utility appears.
