Download the Windows Installer and follow instructions..  I know almost nothing about Windows so no help here other than to say I did successfully install the IDE on Windows 10.

  NOTE: MounRiver.com does NOT use https://

I actually had to download the ZIP in Linux - Windows wanted 1 1/2 hours to do the download - Moun River is obviously not a powerhouse on the web.

Download Moun River for Linux and extract it.  Read the README - you will need to run a script before installing.

The actual IDE is an appImage -- see my Instruction on creating a launcher Icon for the gnome desktop.

There are 2 types of launcher that can be created for the gnome desktop.

Local Installation: if you want to install the IDE for a certain user only.

1. Copy all of the Moun River extracted files to: ......  TBD

SystemWide Installation: to allow any user to execute Moun River.

1. Create directory: sudo mkdir /opt/mounriver
2. Copy all of the Moun River extracted files to: /opt/mounriver
