we're running a win 2000 pro network and i'm trying to push a script over our network to install a new software package. i have an .msi created but when i launch it, gives me the error "the installscript engine is missing from this machine. If available, please run ISScript.msi or contact your support personnel for further assistance". i tried to download ISScript, install it and register it but i still get them same error. any ideas?
