Well I couldnt get kixtart to get past the hidden file state. So I used it to create a batch file that worked just fine.

Thanks

This kixtart script is pretty fun to figure out.

 Code:
Break on
;open file to create bat file
OPEN(1,"\\server\KiX2010.460\dosdel.bat",5)
;Try to open list with computer names
If Open(3, "\\server\KiX2010.460\allpc.txt", 2) = 0
	;List successfully opened. Do more stuff.
	;Read first line from the list.
	$computer = ReadLine(3)
	;If no error occurred and the line is not empty more stuff.
	;Enter a loop until the line from the file is empty or end of file is reached.
	While @ERROR = 0 AND Trim($computer) <> ""
		;Read sysroot from the registry.
		$sysroot = ReadValue("\\" + $computer + "\HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion", "PathName")
		;Split sysroot on : and join it with $.
		;This just replaces c: with c$.
		$sysroot = Join(Split($sysroot, ":"), "$")
		? "Deleting Temp Files From " + $computer
		;Set variable Y
		$Y = "\\" + $computer + "\" + $sysroot + "\Installer\*.msp"
		;Show $y on the screen.
		?$y
		;Write Delete stuff from the remote machine to batch file.
		WRITELINE (1, "Del \\" + $computer + "\" + $sysroot + "\Installer\*.msp /f /q" + @CRLF) 
		;print error record
		?@error
		?@serror?
		;Read the next line from the list.
		$computer = ReadLine(3)
	Loop
	;Close the list with computer names and batch file.
	Close (3)
	CLOSE (1)
EndIf
