xp pro won't boot

I have a computer that won't boot after an electrical outage. the error
message states "explorer.exe unable to locate componet" "this application
failed to start because 'cryptui.dll' was not found".
the file 'cryptui.dll' is in the system32 folder but windows won't boot
because of the above message. I have tried to rename and replace the file but
can't. I have tried replacing it using recovery console, putting the hard
drive in another system as second drive the trying to copy the file but
windows will not let me do anything.
this file from what I have read is part of a service pack.
Is there any way to fix this problem without reformat and reload windows xp
pro.

Thanks
Danny

Try the repair installation option. You'll need to install service packs and
other updates but you'll keep your data.
