Has anyone else experienced this?

I have been using Mathcad 15 on a daily basis for years. I used it yesterday. Today when I clicked on it I got a popup saying the hostid did not match that on my computer. I looked at the host ID in the license and sure enough it did not match that in my laptop (ipconfig/all). How could this have occurred and how can it be fixed ? Is it possible that automatic windows updatse could have caused this ?

I had the same problem. PTC does not seem to grasp the fact that a windows machine can have multiple physical addresses. If the PTC license module finds the one it was registered to first everything's fine, if it finds one of the others it thinks the software is not licesensed. You have to go into the PTC website and transfer your license to the the other physcial address.

I don't know why PTC seems incapable of fixing this. Seems it would be a simple matter to scan for all physical addresses to decide if the software is licensed to that machine rather than stopping at the first one. Or even better yet,just issue a hardware key so you can run one license on any machin with MathCAD installed.
