So is it a good idea to run the software in a sandbox?

Like sandboxie? Not really. Most common sandbox software does not prevent the software from reading your drive contents, it does however prevent it modifying it. So, if you have things to hide or simply don't want them scanning your drive, the answer is no. If you only don't want them to fuck with your data the answer is yes.
