Hi Jim.
Good question. It all depends on what version you had when you purchased back in 2012. Current versions for WTP, LP, and 3DDP is 3.x
Segment Pro is 1.x
If your license was for 3.x for WTP and LP then the answer is Yes your code will work if you download the software from the website
SP did not exist back in 2012, so your license code should work if you download the software.
Lloyd has stated before that updates are free and are downloaded from the Download page.
When a new version of the software is released, that is version numbers change from 1.X to 2.X (for example), then there is a cost. It basically then is not an update but a major revised version.
From another thread Lloyd stated:
"I have always used a minor/major approach in my software companies. All minor upgrades (3.0 to 3.1, for example) are free. Major upgrades are purchased (3.0 to 4.0). ……….."
