Valheim server install failed

Make sure you have .NET 5 installed, you can see what you have installed with "dotnet --info"

Could you provide logs from the first steps?

Hello I have the same problem I have got a dedicated server pc. installed umod through powershell ok (Well I think it did) but when I try and install it through cmd to the server I get this.

C:\Valheim\steamapps\common\Valheim dedicated server>umod i valheim -P
Could not execute because the specified command or file was not found.
Possible reasons for this include:
* You misspelled a built-in dotnet command.
* You intended to execute a .NET program, but dotnet-C:\Users\J4CKS does not exist.
* You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.
Valheim server install failed
App install successful

To install additional .NET runtimes or SDKs:

Okay, now "dotnet tool list --global"

Then, assuming uMod is installed, "umod --version"

Then update the tool

dotnet tool update -g uMod --version "*-*" --add-source

any try to install the game again..

C:\Users\J4CKS Server>umod --version
uMod Agent - (1.2.269)
No game installation found. Use "umod install --help" to install a game server.

running the update now

Ok Im still getting the server insall failed

C:\Valheim\steamapps\common\Valheim dedicated server>umod --version

I added a "--debug" option to "update"/"install" command. If you update the agent, by running that "dotnet tool update" command above again, and then run "umod install valheim -P --debug" it should give you some additional output about exactly what DepotDownloader command was invoked.

You can then take that, share it with us, and/or run it manually. It would be something like..
"dotnet /path/to/DepotDownloader.dll -app APPID (other arguments)"
