Installing Mono did not Fix my .NET 4.6 Problem... Did I do it Wrong?

[GPWR]

I'm running Debian Bullseye on an amd64 system. New to Linux, but having lots of fun.
So... I have a clean Wine install and a 64bit Wine prefix with pretty much all default settings but for the fact that I made it a Windows 10 layer rather than Windows XP, which was the default.
I'm trying to install a DeepL client. You can find the Windows download at deepl.com. It's an EXE installer. I run it in wine via the right-click menu in my file explorer and I get the following:

Install .NET 4.6
The application requires the .NET framework. Click the Install button to get started.
This application requires the .NET framework 4.6 or above. Clicking the Install button will download the latest version of this operating system component from Microsoft and install it on your PC.

I know how to install .NET via Winetricks. I'm simply not interested. I usually only install non-free software as a last resort, with Microsoft, of all things, being no exception.
I heard Wine Mono sort of acts as a .NET framework. So I installed Mono via the following command:

Code: Select all

sudo apt-get install mono-complete

No worky. I get the same error message.

Thanks in advance for any help, a great last week of advent to y'all, and God bless you.

You are confusing two things: Mono and Wine-Mono.

The first is an open source implementation of Microsoft's .NET Framework which allows .Net applications to run on Linux. You did install this one with apt-get

The second is a version of Mono made specifically for Wine. It allows Wine to run (some) .Net applications.
This version is automatic installed when you start a program with Wine for the first time.
Run

Code: Select all

wine control appwiz.cpl

to make sure Wine Mono is installed.
If this did not happen, you can find a guide to download and install the wine-mono .msi file here.

Back to the real problem. The DeepL client needs the real .Net Framework. Use winetricks to install dotnet462

I’d avoid dotnet point releases like 462/472 etc as those love to hang. Instead use the next none point releases 462 use 47, 472 use 48 as those are less prone to hanging.

Thank you so much for both your answers.

Given this, I won't even bother installing Wine Mono. Up to now, DeepL is the only thing I need which requires .NET.
By the way, how did you figure out that DeepL needs .NET? Is it just test-and-see, or is there another way of knowing?
Thanks again for your response. It's really appreciated.

Thanks for letting me know! I was not aware of this.

Happy holidays.

Indeed, this is just trying.
You start with a clean Wineprefix. If everything works then you don't need to do anything. I it doesn't, often the error messages in the terminal output tell you what went wrong.

Awesome. Thank you for this information.
Peace be on you.
