Window xp installer problem
 

i am not able to install things. i get this error and i have windows xp.

"error 1601: The window installer service cannot be accessed. this can occur if you running windows in safe mode or if the window installer is not currently installed.



i also try reinstalling windows xp, hoping it will replace any file i was missing, but i still getting the same problem.

anybody know how to fix it without having to do a clean install?
