Wow! (pun intended)

Thank you very much. For anyone who happens across this thread, the issue and solution can be seen by running the following very simple script:
 Code:
? "(Using KiXtart command to reset file attibutes)" ?
$rcode=setfileattr("%systemroot%\system32\kix32.exe",0)
@serror ?
? "Checking attributes of all k*.exe files from KiX:" ?
shell "cmd.exe /c attrib %systemroot%\system32\k*.exe"
? 
"Now turning off Wow64Fileredirection." ? ?
$rcode=setoption("Wow64FileRedirection","off")
? "(Using KiXtart command to set kix32.exe system hidden read-only)" ?
$rcode=setfileattr("%systemroot%\system32\kix32.exe",7)
@serror ?
? "Checking attributes of all k*.exe files from KiX:" ?
shell "cmd.exe /c attrib %systemroot%\system32\k*.exe"
? 
? "(Using KiXtart command to reset file attibutes)" ?
$rcode=setfileattr("%systemroot%\system32\kix32.exe",0)
@serror ?
? "Checking attributes of all k*.exe files from KiX:" ?
shell "cmd.exe /c attrib %systemroot%\system32\k*.exe"
?

Note that if you run this on 32-bit Windows, there will be no change. On 64-bit Windows, file redirection and the use of setoption() to disable it is seen.

Thank you again!
