Server Application Error, ASP can't run

[Alan]

Hi experts,

when accessing localhost, Server Application Error is returned and ASP
and ASP.net can't run. From KB HOW TO: Troubleshoot ASP in IIS
5.0(http://support.microsoft.com/default.aspx?scid=kb;en-us;q309051),
It is asked to reinstall com+
(http://support.microsoft.com/default.aspx?scid=kb;EN-US;301919). When
following the procedure, during add/remove
Windows components, the following error appeared:

Sub-component COM+ raised an exception while processing the
OC_COMPLETE_INSTALLATION setup message.

d:\nt\com\com1x\src\complussetup\comsetup\csetuputil.cpp (line 3406)

Error Code = 0x8007007f

The specified procedure could not be found.

Failed to load the library 'C:\WINDOWS\System32\comuid.dll'.

The problem persists after serveral trials. Please help, and thanks in
advance for any kind help.
