Usually, the applications are downloaded in Computer > Local Disk (C:) > Users > Computers > Downloads folder. If you can't find the product there, I suggest you to do a search on your computer using the search engine from the Start Menu. If there is no trace of the product you can re-download it. Fill up the fields from the official web page and press the re-download button. At the beginning of the download process you can select a place to save the files using the Save As option.
