Help! I have been trying to download solidworks onto my computer. I can start the setup file, but part way through the download, it says that a version of bonjour (whatever that is) has already been downloaded: it then says I can continue downloading, but might run into problems.

I then run into problems, as I am prompted that the "Windows Installer for this product component did not run as expected: LaunchConditions"

What should I do?
