You can choose either the executable program or the entire installation CD for MC10, MC11, and MC12. If you have an earlier version, download and use MC12. These new versions do not require the security key, so they make Micro-Cap free to the entire engineering community.
Thank you for the honor and privilege of serving you for the last 39 years.
Every little bit helps!
