I am trying to install umod for Valheim. First step is getting uMod to work which I can not. I Am running Windows 10 pro 20H2.

I have done this on a clean install of windows and I get the same error. UMod is not reconized. I restarted the PC and terminal.

This is what my terminal looks like:

PS C:\WINDOWS\system32> &powershell -NoProfile -ExecutionPolicy unrestricted -Command "[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12;&([scriptblock]::Create((Invoke-WebRequest -UseBasicParsing 'https://umod.io/umod-develop.ps1')))"

Ive reinstalled twice for a sanity check and nothing. 

Update:

I tried to manually force the templates update with

dotnet new -i "uMod.Templates::*-*" --nuget-source https://www.myget.org/f/umod/api/v3/index.json

This is what happened

PS C:\WINDOWS\system32> dotnet new -i "uMod.Templates::*-*" --nuget-source https://www.myget.org/f/umod/api/v3/index.json

Did you close an reopen the PowerShell window as the message mentioned?

Yea i even restarted my PC. Im not as good as you all with .NET framework but im thinking it has something to do with the templates not updating?

That second error you're getting is due to a bug with "dotnet new" and is safe to ignore, also it will no longer happen with the most recent installers.

The "--nuget-source" and "--add-source" options are no longer required (the source of that bug).  I have updated the installer scripts and the installation guides to reflect this.

The latest installers will add the nuget source globally, like so..

dotnet nuget add source https://www.myget.org/f/umod/api/v3/index.json --name uMod

Regarding the "umod" cmdlet not being available, I would double check your PATH environment variable to ensure it points to the right place.  The dotnet installer (provided by Microsoft) is supposed to do this, and we attempt to do it again if it fails, but sometimes they both fail..

PATH should have:
"%USERPROFILE%\.dotnet\tools"

Which roughly translates to..
"C:\Users\Calytic\.dotnet\tools"

Thanks! I'm sure that should fix it I just didn't know how. I'll give it a shot when I'm home in a couple hours 

Merged post

It worked Thanks! 

For anyone who searched and found this. 

1. Open run

2. Type sysdm.cpl

3. Go to advanced

4. Click Environment Variables

5. Double click "path" under system variables 

5. Click new

6. Make the path "C:\Users\*account name*\.dotnet\tools"
