Win7 Guest cannot add shared folder to the guest Win7 Library because it is not indexed

I just want to have with Fusion Pro, exactly the same feature that Parallels has, to evaluate evtually to move form Paralles to Fusion.

I want to add my Host Mac Folders to the guest Win7 Libraries (and viceversa Win7 Folders viewable directly into my Mac Finder).

Let's go step by step.

Adding a Mac Folder viewable inside the guest Win7 Guest through the shared folder mechanism, raises the error mesage: "This network location can't be included because it is not indexed".

Anyone who can advise me about it?
