Scripting

Hi everyone, i hope you can help me. I've been playing around with scripts to downgrade about 200 machines that accidently were upgraded to either IE 10 or IE 11. Because of compatibility issues i need to downgrade and install IE 9. The batch file i have closes IE and runs the uninstallers, if i run the batch file manually it works but when i push it through k1000 it seems to skip the batch and go to the restart. I've read a few places on here that mention to run the script using psexec, unfornately i'm new to all this scripting and don't know how i would get that to work on over 200 machines. Below is the script i'm using, i would appreciate any help i can get.
