Changes

I know the remove command looks strange - I took it from registry. Don't know why default parameter /x{INSTALL_ID} doesn't want to work as it should, looks like it waits for confirmation 'are you really sure, you want to remove this product' - msiexec should automatilcy say 'yes'. Possible .. but it doesn't :( Possibly there's more then one way to do this right - this one works OK for me.
