Hi @ashkaan ,
I do not think you should change ownership to roop, I would leave the ownership as it defaults by SAS installation.
There is nothing wrong with this message, it is just an informative message for whom triggers the utility, but the utility still runs OK. There is a reason for having this message: you will run the tool with elevated privileges and you will clean the work folders not only of your user, but for all the users. Again, just a positive warning, not an error.
