I installed it, and repaired it twice. Still doesnt work

[mairaw]

Hi @26mmangan! I'm sorry to hear you're running into problems.

This might be an issue with PATH.

Check the output of the where.exe dotnet command and if your system is x64 and the x86 path returns first, please follow the steps at #5962 (comment) to fix the issue.

Let us know how that goes.

[26mmangan]

Ive reinstalled it a few times,

Doesn't look like it's working

[richlander]

Looks like you are in the user space. You want the system one. You appear to be looking at the first box. You want the second one.

[26mmangan]

[richlander]

Can you show your system path?

Also, show the results of this:

C:\Users\rich>where dotnet
C:\Program Files\dotnet\dotnet.exe
C:\Users\rich>dotnet --version
8.0.100-preview.1.23115.2

[26mmangan]

[mairaw]

Can you open the one I highlighted below?

[26mmangan]

[mairaw]

The x86 is listed first there. Can you confirm what kind of machine you have?

Type system type on your windows toolbar and open the System Information app.
If System Type is x64, then you need to move down the x86 entry to be the last one.

[26mmangan]

I have a x64 machine. Will do.

[mairaw]

Let us know if after the change, you can type dotnet commands. Make sure to open a new window.

[26mmangan]

[mairaw]

what where dotnet returns now? and did you make sure you opened a new window after you applied the changes to path?

[26mmangan]

Yes, I used a new window

[mairaw]

but x86 is still showing up as first, so maybe the changes weren't saved, Can you double check the environment variables again?

[26mmangan]

🤷‍♂️

[mairaw]

Usually that step by step works 😢 @richlander any other suggestions?

[richlander]

Make sure to close the command prompt after changing the values in the environment variables.

[26mmangan]

I did, I restarted it twice

[richlander]

You can just delete the x86 one. It isn't useful.

Also, it is dotnet --version not --ver

[26mmangan]

Done, alright thanks

[26mmangan]

[richlander]

And type where dotnet again to see where that is coming from.

[26mmangan]

[richlander]

That is very odd. Something is clearly injecting the x86 path. Which .NET versions do you have installed?

Like this:

[26mmangan]

[richlander]

Can you double check that the x86 is not present in both the System and User PATH Environment variables?

I have no idea what is causing this. It is very odd.

[26mmangan]

[richlander]

That looks correct.

Can you show the output of set from your command prompt? It's really only the PATH variable I'm interested in.

[26mmangan]

[richlander]

That looks right.

Please show me where dotnet now and dotnet --info

[26mmangan]

[richlander]

This is the problem. You have an old 5.0 install on your machine that you need to remove.

Perhaps this was installed by Visual Studio. If you have that, can you go into the Visual Studio Installer and remove it from the installed components?

[26mmangan]

How do I do this?

[mairaw]

But the set path above is showing x86 first @richlander. Is that expected?

[26mmangan]

This is my extensions list for VS Code if you need it.

[mairaw]

This is VS Code. Do you have Visual Studio also installed?

[26mmangan]

Naw, just VS Code

[26mmangan]

@mairaw @richlander

@26mmangan it appears that you have x86 versions of .NET 5.0 WindowsDesktop runtime, which also carries NETCore runtime.

The easiest way to remove would be from Control Panel or Settings app, but if they don't show there, here's the alternative.

1. Download the following installer: https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/runtime-desktop-5.0.10-windows-x86-installer

2. Run the installer. You should get a dialog that says Modify Setup, with multiple options, one being Uninstall - proceed with that. In some rare cases, it's possible that you would see a regular dialog for first-time installation - you would proceed to install the product. After that, you'd run the installer again and choose Uninstall.

After .NET 5 is uninstalled, open a new command prompt and try the commands that were failing, or producing unexpected results, previously, i.e. dotnet --version and dotnet --info.

[26mmangan]

Successfully uninstalled, and reinstalled, same issue.

[richlander]

You re-installed .NET 5? Is there a reason for that? Also, you seem to have 5.0.10. Is there a reason you are using that version? If you need .NET 5, can you install 5.0.17? https://dotnet.microsoft.com/en-us/download/dotnet/5.0

[26mmangan]

No, I re installed .NET 6.0.407


I'm not sure why .NET 5.0 is on my computer, I haven't installed anything other than the above

[richlander]

You still have 5.0 installed. Did you try running the 5.0 installer and choosing uninstall?

[26mmangan]

Done.

[NikolaMilosavljevic]

@26mmangan can you share the outputs of dotnet --info and set PATH commands?

[26mmangan]

[NikolaMilosavljevic]

Thanks - it is odd. I understand that you installed and uninstalled 5.0.408 SDK, but have you tried to install (or repair) x86 version of 5.0.10 WindowsDesktop installer, and then run the same installer to uninstall it? I've shared the steps 2 days ago: #8347 (comment)

It would be good to go through those steps and see if there is any improvement in dotnet --info and dotnet --version results.

I presume you are starting a new command window after each of these install/uninstall operations, as that is necessary to get the updated values of environment variables, like PATH.

[26mmangan]

Oops, I installed and uninstalled 5.0.4... Here:


It works! I think...

[NikolaMilosavljevic]

That's great news!

[richlander]

This looks resolved. Sorry that this was so hard.
