Hi,

I work for Schrader International, Inc. and we have a license that allows us to load Solidworks at home.  I am using the 32-bit version of 2012 right now.  I just upgraded my operating system to Win 7 so that I could install the 64-bit version and improve performance to what I am used to at my work computer.  All went well until I tried to activate the new installation.  It failed to activate.  What is the issue?  Do I need to uninstall the 32-bit prior to activation of the 64-bit?
