Mathcad 7 Prime 7 Installation Issues

[KK_10118479]

Hello, I tried to download Mathcad Prime 7 but in the installationassistent the status of the application is "not permitted". How can I avoid this?

Do you have a license for Prime 7 (or 8 or 9)?

(Then you should be able to download the installation source from here.)

Do you have Prime 8 or 9 already installed on your PC?

(You can install multiple versions of Prime on the same computer, but you can only install them in sequential order, from lower to higher version).

Success!
