So I would like to install Open Hardware Monitor. I downloaded it and extracted the files (right-click, 'Extract here', not $sogijdsfg -xcv /sdflsa/rtyf). There's a .exe file but that only opens a folder with strange files. How do I install and run the program?
As already said, you cannot install .exe win32 executables on Linux but please be informed that Open Hardware Monitor is also available for Linux, in fact:
On Linux systems the Open Hardware Monitor requires Mono with WinForms.
sudo apt install mono-complete
