When installing an hp psc 950 printer from the CD, the wizard runs a few second and immediatly displays the message "error 1327 invalid drive H:". Sorry to insist, but I'm blocked. Thanks for helping me

This error occurs when the computer does not recognize the drive letter that you are installing the program into. To fix this problem, you will need to temporarily change the letter of you CD-ROM drive. Here is what you need to do: 1. Right click on "My Computer" 2. Select "Properties" 3. Click on the Device Manager tab 4. Click on the "+" sign next to where it says CD-ROM drive. 5. When you click on the plus, you will see a new item under where it says CD-ROM drive, which indicates the brand name. Right-click on the name. 6. Select Properties 7. Click on the tab at the top that is labeled "Settings" 8. In this window you will see a section that says "Reserved drive letters" 9. Depending on your error, you will need to change the letter that appears next to "Reserved drive letter". If the error was "Invalid drive E," then change the drive letter to the letter E. If the error referred to drive "D", then change the drive to D. 10. Press "OK" 11. Install the program 12. Once the program is installed, you can repeat the above steps to change the drive letter back to its original setting.
