Patching WMSDE with SP4

Can anyone tell me whether WMSDE (which installs with WSUS) can be patched?
I am trying to apply MSDE SP4 to the WSUS instance and it returns an error
message stating that SQL server is not installed.
Thanks in advance for your help.
Hi
You may want to print the exact error message, but any instance of SQL
Server should be patchable with the correct patch file.
