Enabling Quartus II 12.0 SP2 64 bit version (Web Edition) w/ Windows 10 64 bit OS

I have installed quartus ii 12.0 sp2 web edition. I am running Windows 10 64 bit Pro OS.

From what I understand, I need to compile the vhd files in Quartus II in 64 bit mode to properly operate my EP2C35F672C6 board of the Cyclone II family. However, when

I installed Quartus II, I only have the option to run it in 32 bit mode.

At school, I have the option of both 32 and 64 bit modes when I search for it after pressing the windows key. My

instructor has told me to only use 64 bit mode to avoid issues when implementing my hardware.

Is there a way to go about installing or enabling 64 bit mode?

I was never given the option to download either 32/64. It was a single package, so I assumed that it would come with both.

Also, I intend on installing the free edition of ModelSim 10.0d. Will I encounter a similar issue?

I have not been able to find ample information on this specific topic elsewhere. I would greatly appreciate any feedback as I would love to be able to work on my projects at home.

Thank you!
