I run Mathcad 15 on a virtual Windows XP machine within my iMac Sierra. I have not used Mathcad for more than a month. when I came to use it this afternoon (9th June 2017) I could not start it up. Can anyone direct me to someone who might be able to help, e.g. a help department of PTC, please?
Thank you for taking the time to reply to my plea.
I get no error message.
However, I have been reviewing the situation and it seems that, although I paid my annual renewal fee to Parallels, which facilitates the running of Windows XP as a virtual machine on my iMac, when queried on the net the answer came back that my account had been terminated, despite what I thought was a genuine payment.
Since I got that news, I have checked and found that I could not run Outlook, or my old-fashioned, but serviceable Fortran 4 Power Station, by Microsoft.
I suspect that the problem lies with Parallels and I await a response to a query I have made to them.
Again, thanks, but I think that I started off on the wrong track.
