I bought PSE and have been short sheeted by Adobe. They only let me use the software on two machines, with the generous option of activating/deactivating licenses on any number of machines as long as no more than 2 are active at any given time. The catch there, other than the aggravation of going through the activate/deactivate process is that even then they only let you do it 25 times IN YOUR LIFE. Are there any workarounds anyone knows of? (Yes, I know I could buy the license again, but that seems like they'd be getting my pound of flesh twice for the same product.)
I'm not sure I understand the problem. You bought the product with a two machine limit, but want four machines. Buy another copy, and you are all set. You are not buying the same product twice. You are buying the ability to install it on two additional machines. PSE is a very inexpensive product. You cannot expect to average the price down by installing on a bunch of computers.
Asking for tips on how to defeat the license does not fly on the Cow forums.
