Installing Mathcad prime 8 stops after "exctracting"
I can't install Mathcad Prime 8. I have alredy Prime 7 (with watermark) and it works good.
I can download the installer but when i launch "pim_installmgr_mathcad.exe" the installation process just stops after "extracting" window reaches 100%, and there are no installer window open after that.
I have tried it many times and as administrator, but always same problem.
