Check http://www.mvps.org/scripting/faq/wshfaq.htm. Excerpt:
Q: I get an error when I run a script on Windows XP that looks like this: "The procedure entry point DoOpenPipeStream could not be located in the dynamic link library ScrRun.dll".

A: It's very likely that some other application you have installed put an older version of scrrun.dll on your system, causing this error. The version in %windir%\system32 should still be the correct one (it's a protected file, so it shouldn't have been overwritten), so you can probably just re-register it and all should be well. Type "regsvr32 scrrun.dll" from any command prompt. The version number on that file should be 5.6.0.6626. (Mike Whalen)
