Net framework 928366 encountered a problem

I have 4 servers running Windows 2000 SP4 with Citrix. The Windows

drive is W: and there is no physical C: drive as that maps to users

home directory.

When running NDP1.1sp1-KB928366-X86 from either Automatic Updates,

WSUS, or manually I get SL9E.tmp has encountered a problem and needs

to close. We are sorry for the inconvenience. The file name changes

but is always a .tmp.

If I extract the MSP, I can apply the MSP just fine. But I need to

figure out what's wrong and fix the core problem. There are other

patches having issues.

I turned on in the HKLM/...Windows/Currentversion/setup/debug to ffff

but the logs don't really seem to indicate anything. There are errors

but they are things like searching for Windows 2003 SP1 indicator file

(this is 2000) and searching for FRS which doesn't exist on 2000.

Any ideas? Thanks!
