I've started the installation process for MathCAD Express, but when I reach the "Application Selection" step there are no applications to choose from. I'm not sure how to correct this issue.
Refer the below link for for step by step procedure to download the trial/express version
I just asked a friend if he could try to install it on his PC, same issue, i suspect that the install package that is downloadable doesn't include the mathCAD file.
I tried to download Mathcad again, but this time I opened the installer as an 'Administrator'.
Believe it or not, I had a list of applications to choose from. It's installing now.
If you are still having issues try opening the installer as an administrator.
Hopefully that work for you also.
