Salt IIS configuration fails -

i trying configure iis on windows 2012r2 x64 via salt. downloaded , linked salt-contrib. when run:

salt-call --local iis.apppool_list 

i getting following error

[error 2] system cannot find file specified

but when running

salt-call --local cmd.run "c:\windows\system32\inetsrv\appcmd.exe list apppool" 

it displays configured apppools.

do have ides why first command fails?

i haven't had time set environment test, i'm guessing it's bug in code.
