The VISIO 2010 copy I purchased for 1/4 the MS price does not work with Office. It seams that for that money I have bought just VISIO, and nothing else. It reinstalls every time I run it, MS Office does not recognize it and no help files are available. I tried registry fixes found online, reinstallation and Software King technical support which was no help. Beware of what you are getting as this is not a "working" program across all MS products. No refund if you buy downloaded software. Not happy, but I got what I paid for. If I would have known I would not have purchased it. I will not be buying another other of their "products".
