local port missing in registry

[Guest]

XP SP2: wizard unable to install to LPT1 because cannot find port. How do I
recreate the missing entry? LPT1 okay in device manager and BIOS.

This sounds like another application removed or replaced the spooler binary
registry setting for local ports.

I have seen issues when the LPT ports are no longer listed by the spooler
because another application replaced the registry entry for the dll
controlling where to look in the registry for the port list.
reg key is here:
Local Port should point to this binary
HKLM\SYSTEM\CurrentControlSet\Control\Print\Monitors\Local Port\Driver
reg_sz = localspl.dll


The Port list that the spooler reads at startup is here:
HKLM\Software\Microsoft\WindowsNT\CurrentVersion\Ports

LPT ports should be listed here
