PTC MathCad Primr 8.0.0.0 .exe File opening, extracting and closing right after that

[MS_9515513]

I am trying to install MathCad Prime 8.
I downloaded the file from the Mail I got but when I open the downloaded File something gets extracted to about 62% and then the file just closes and nothing happens. I don't know what the error is and I also can't find anything to solve it.
I really need some help!
