Trying to install MathCAD trial
...and the installation download fails on the PTC MathCAD Prime portion of the install. An error message pops up that says "Download Error: Please check the network connection and start the installation again. PTC Mathcad 15 M045 or later is required to convert older Mathcad documents to PTC Mathcad Prime 5.0.0.0. To enable conversion functionality, you can download and install PTC Mathcad 15 M045 or later by visiting http://www.ptc.com/engineering-math-softwsoftware/mathcad/free-triaare/mathcad/free-trial "
I have tried on our office network and outside, so it doesn't appear to be that our firewall is blocking anything. Any ideas?
