Just use Sandboxie for shit like this. It will be a lot easier to setup (takes a few seconds) and it is very good at what it does (allows a program to run and read files it would normally read, but if it tries to write a file it stores the new file in a temporary location -the sandbox- which can later be accessed to pull files out of or just deleted altogether).
Great for surfing dodgy sites on the internet as any malware gets stuck in the sandbox which is easy to delete.
You can also run any program inside sandboxie.
