I am trying to run an sst-run command on my windows-XP machine and I get the following error

(ENV) C:\>sst-run mytest
'sst-run' is not recognized as an internal or external command,
operable program or batch file.

I have installed SST and an running this comman in (ENV)

This is what I get when I try to install SST again:
