How to replace corrupted spoolersv

Windows 7 Pro SP1

Couldn't print and noticed print spooler failed with "Failed to Read description. Error Code 193" as the message. Manual start give Windows could not start Spooler service on Local Computer Error 5: Access denied.

Attempted with both Domain Admin and Local user Admin, same results.

Tried system restore to earlier point but received error about newer system objects.
Tried deleting all printers. Following MS tech net instructions on clearing printer registry entries. Same results
Tried granting authority to spooler folders.

I next tried restoring Windows 7 from the original DVD but it won't because the installed version is newer than the DVD.

I tried copying spoolsv.exe from another Windows 7 system but Windows won't allow replacing the existing version.

Is there anyway to restore spoolsv or any ideas on a solution ?

have you tried sfc /scannow from an elevated command prompt ?
error 193 means it's not a valid Win32 application so it sounds as if the binary file is corrupt

you could also take a look at \windows\system32\spoolsv.exe properties and check the security tab; make sure administrators/system/users all have read & execute

@Seth, yes I ran the src/scannow which indicated that it couldn't repair spoolsv. Tried the restore option and boot from DVD after that. Also gave system user full control on security and tried changing user to admin.

@lionelmm, When booting from the DVD I only get two options: upgrade or install. Don't see a repair option. On the DVD I do see the spoolsv program but it has a mui extension. Is there anyway to extract/convert the mui file to an exe file ?
In the screen before that, on the lower left you will see a link that says "repair options". Have you tried to rename it in safe mode?
Ok finally have it resolved !

Copied a renamed spoolsv.exe from another Win 7 system to the windows directory.

Booted off of DVD in safe mode, took the repair option. From command prompt renamed current spoolsv  and then renamed the copied file to spoolsv.

Thanks for the help @lionelmm.
you're welcome.
