Install program requires superuser

I am trying to install Simplify3D. When I try to run the install program. it displays the logo. Then it asks for the language, when the language is selected. I get an error message saying, "This installer requires root privileges" Please become superuser before executing the installer"

I searched everything I Cound think of, but was unable to find anything useful.

When installing using the terminal start with sudo then the install command example sudo apt install nano. this will put you in superuser/root to grant permissions....hope this helps

Is this only a Notification Windows or can You type in Your Password? Is this Program a .deb File?

I tried to help you but the informations I found were very confusing. In an older thread I found that:

https://forum.simplify3d.com/viewtopic.php?t=16876

Maybe it can help. You would need to adapt it to the version you want to install.
For me, it is not clear if it is better to install it as normal user or with root rights.

Some threads found in internet recommend to make the installation as root user and change it after the installation back to a normal user, others recommend the installation as normal user.

Just a notification window. And it isn't a deb file, or at least it doesn't have that extension.

No joy, I may be missing something obvious. I tried several variations of the program name. It always says "unable to locate package". I even tried
sudo apt install nano, it just says it's already installed. The program I an trying to run is Simplify3D-5.1.2-linux-x64-installer.run.

chmod +x Simplify3D-5.1.2-linux-x64-installer.run

sudo ./Simplify3D-5.1.2-linux-x64-installer.run

@wesoliv429 used nano as an example program demonstratively.
