Error: "Internal error: The Windows Installer for this product component did not run as expected: register_i386_SldShellExtServerExe."

I'm currently trying to install Solidworks Student Design Kit 2014-2015 but keep getting the error in the title. I have tried the 32 bit installation and the 2013-2014 installation (both 32 and 64) but keep getting the same error. How can I solve this?
