.NET 3.5 conflicts with .NET 2.0

[Primalus]

Okay so I've looked through some of the other issues with a similar problem as me, and I didn't understand a thing. I'm using Wineskin to install a program that requires .NET 3.5. Every time I try and install it, Winetricks installs each previous version of .NET (which is expected). When I get to .NET 3.5, the installer crashes and I get this error.

Executing w_do_call dotnet35

error: dotnet35 conflicts with dotnet20, which is already installed.

Winetricks Commands Finished!!

I have no clue as to what I'm doing wrong. I don't quite understand if Winetricks supports .NET 3.5 (which it should, I assume, since it's in the list of things you can install) or if I'm just doing something wrong. I've tried creating new wrappers (which I think is somewhat similar to a prefix?), but I still end up with the same error. I know a little bit about Terminal and how to use it, so if need be, I can try doing it through there. Any help is greatly appreciated, and sorry if I'm being a total idiot about all of this.

EDIT: I forgot to mention that I'm currently using the latest version of Wineskin (WS9Wine1.9.24) and I'm running macOS Sierra (10.12.1).

Try updating your winetricks to the latest version. Also, are you installing dotnet20 via winetricks? The reason I ask is because if you run winetricks dotnet35 (without installing dotnet20) it should pull all the other versions of dotnet including 2.0 on its own...

I have just ran "winetricks dotnet35" on a clean 32-bit prefix and here's my terminal output:

In short, the installation was successful. With dotnet it's best to install it first before installing anything into a given Wine prefix as dotnet versions installed by Windows programs may not register properly in Wine.

Alright so I've made a new 32-bit prefix and did the command that you mentioned after launching Wine Devel (winetricks dotnet35). My winetricks is already updated. Here's my terminal output

EDIT: Forgot to mention that I don't know what to do after this. It doesn't look like it installed properly.

That's definitely not the latest winetricks (it may be the latest release, but it's missing OS X fixes that are in master).

*** error for object 0x401c1500: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug

is also concerning, that may be from wineskin, not sure, I'm not familiar with it.

Anyway, there's nothing about a conflict in that output. Definitely looks like a buggy wine build, IMO, but I'm not certain.

Try asking Wineskin?

I've given up on Wineskin for now and I'm only using Terminal. I thought I had the latest winetricks, turns out I didn't (thanks for telling me). I installed the latest (I hope) via Terminal and wget and created a new prefix once more and ran the command again. This time, I got

I took a look at the messages it was spitting out and saw that I could try adding '--no-check-certificate' to attempt to get it without viewing the certificate. I tried typing it in like

winetricks dotnet35 --no-check-certificate

and got the exact same error.

I also did ask Wineskin a few days ago on their forums. No response yet.

Alright, so I was finally able to install .NET 3.5. I re-installed Homebrew, Wine, and winetricks (some of that was probably unnecessary). It turns out I had to install it in a regular Terminal window, and not through the Wine Staging Terminal window. So that means that winetricks dotnet35 works. Thanks for all of your help!
