when i download a 2012 file from this, and try to open it, solidworks always says future version even though i have the 2012 version, any know whats wrong??
BackWorks is a SolidWorks Add-in that will allow you to save your files back as far as version 2012. It Is also able to open and save future versions of SolidWorks.
This product can be downloaded from the link below and has a free trial offer. BackWorks has worked great for me in the past.
