i have a problem when i try to deploy a .msu patch which for vista pc using
sms2003.

An error occurred while preparing to run the program for advertisement
"HQ12018E" ("HQ1001A3" - "os-941001"). The operating system reported error
2147942487: The parameter is incorrect. Additional program properties:
Command line: KB941001.msu /quiet
Working directory:
Drive letter (? = any):

Possible cause: This message most commonly occurs when the program's
command-line executable

Did anyone know what is the problem in there?
