    Unable to install printer into Windows Vista

    Whenever I try to connect my PC running on Windows Vista, I keep getting the error message “operation could not be completed error 0x0000046a”. I need to print an important document saved on my PC. In what way can I install it?

    You can resolve this issue by increasing the value of IRPStackSize in registry. Press the ‘Start’ button and select ‘Run’ option from the start menu. Type regedit into the field appears on the screen and press the ‘OK’ button. Once you can view the registry editor, navigate into HKEY_LOCAL_MACHINE\System\CurrentControlSet\Servic es\LanmanServer\Parameters from the left pane. Double click on the IRPStackSize value to change it. If you can’t view the IRPStackSize, right click on the right pane in Parameters folder and select ‘New’ option. Click on DWord Value and enter IRPStackSize into the corresponding field. Double click on IRPStackSize and change Base to decimal. Enter a value larger than the listed value into Value Data box. Quit the Registry Edit and restart your PC.
