Question
Mathcad 15 License
My Mathcad 15 license is no longer functions for last several days (offers to open License Wizard every time when starting. Despite pointing to correct license file, it does not work on next attempt to start). The same license file worked normally for years. The same license file works fine for Prime 5. cpuid.exe returns a HostID matching the license file. I downloaded a new license file, also not working. Nothing else changed on computer as far as I know. It does not appear I can get PTC support as a legacy user. Any ideas anyone has would be greatly appreciated.
