MMW license for version 4

[jward52]

I own licenses for both version 4 and 5. I want to put version 4 on a computer I'm going to use for an AV project but it tells me the code is invalid. Why is that?

Normally because the wrong License Username (usually full name) is being entered: https://www.mediamonkey.com/support/kno ... key-usage/
