This ties the license to the PC’s unique hardware ID (motherboard serial, HDD serial, etc.).

Best for individual PCs. It is often linked to the 32-bit version of the application.

There is no avoiding it—if you want to use Omron hardware, you need this key. The software is top-tier engineering tools, but the licensing mechanism feels like a relic of the early 2000s. I highly recommend opting for the Hardware Key if you travel between sites, but keep it safe; that little USB stick is worth thousands of dollars.
