STK 64-bit Install

All releases of STK 12 are 64-bit only installs.

STK 11.4 thru STK 11.7 are 64-bit only installs. Releases prior to STK 11.4 included a 64-bit or 32-bit option. 

By shifting to 64-bit, you have better performance, faster processing, and an optimized software. With a 64-bit install, you can use more space on your machine for your analysis. STK 32-bit limits you to a few GB. STK 64-bit lets you use up to 128 TB of RAM. In a 64-bit system, you can expect more reliability with your calculations, higher precision, and higher fidelity with your analysis.
