I bought a textbook that came with an unused CD of Mathcad 15 M010; never used MathCad but it seemed interesting. Tried installing it on my Windows 10 laptop; it told me I was running Windows XP. Followed directions found here to fix that; it apparently installed correctly and took the product code,, so I assume I have a license. However when I try to launch the program nothing happens. Things I've tried so far:
1) run as an administrator
2) run in Windows 7 compatibility mode
3) uninstall and reinstall
The only thing that has any effect at all is running in administrator mode, which gives me a splash screen that says "Do you want this software from an unknown publisher to make changes on your computer?" but nothing further happens after that. This isn't a desperate situation; I'm not trying to use the software for work or school, but I wouldn't mid it if it would work.
