Hy guys, Im putting this information here because it can be useful to someone. Thats the deal... parallels tools try to put your shared folder system in expression blend... it is not allowed by the software (you did a "unknown path format" message)... so to use shared folders , to share your projects with your mac you have to use this path: Z:\Desktop not this one: \\.psf\Home\Desktop I know is too simple, but it took me days!! and this is very important to make Expression Blend to work properly in parallels.
