I used the 30-days free trial of MC15. During the MC15 installation I noticed that my existing MC14 was removed by the installer (why does PTC do that???). When the 30 days were over, MC15 showed me a notice to that effect. So I reinstalled my MC14 again to continue my work, but now my MC14 shows me that exact same notice and refuses to run. I uninstalled MC14 and MC15 completely and installed MC14 again, but that didn't help!...
What must I do to get my MC14 running again?
++Lodie.
P.S. I work under Windows 7.
