i downloaded ms office 2013 pro plus sp1 from a link from MDL. installed. but visio viewer didn't installed. i then many times repeated this and found the same result. i also tried custom installation selecting visio but even then it didn't installed. it was VL edition
i could not install it. i dont doubt iso image as i downloaded from a link here published my November ra1n. it can't be corrupt. but yes....word, excel and power point are nicely installed.
