New Installation (Windows 11) - Nothing Works

[Flagelmann]

Question

Hello,

I would like to ask which kind of additional packages/dependencies/combinations are required to make opencode working on a simple Windows 11 system.

I'm asking this because I tried to install opencode for the first time on a Windows 11, clean, working, first using the Opencode Desktop App and trying to configure manually ollama local in it but without luck at all (thinking wrongly it was simple as in OpenWebUI).

Then I realized that I needed to install first npm, then running "npm i -g opencode-ai" and finally open "opencode" in Windows Terminal.

Unfortunately the result is the following:

Basically after calling "opencode" in Windows Terminal nothing run, the "opencode TUI" does not open...and Windows Terminal hangs.

Now, is there any hidden, not documented, setting and/or package or small specific dependency arch-based that I should install or configure manually to make opencode TUI working at least (I am worried about the Opencode Desktop App at this point, if it is so difficult to make it works from scratch on a clean system).

Many thanks

Regards

This issue might be a duplicate of existing issues. Please check:

• Windows: opencode CLI hangs at startup when running internal npm list / npm config get registry #11657: Windows opencode CLI hangs at startup (same symptom: installed via npm i -g opencode-ai, ran in Windows Terminal, process hangs indefinitely with no TUI shown)
• Using the opencode Windows Terminal, after default installation and startup, Waiting to see the error message. #13129: opencode Windows Terminal hangs after default installation and startup (same symptom: TUI does not open, terminal hangs)

Are you on windows arm64?

No, Windows 11 x64, not arm-based.

Also, to make it clear:

Update: the issue is driven by using a RAMDisk on the system.

Specifically opencode is incompatible and it does not run when using a RAMDisk as a TMP/TEMP system location.

It leads to the following error in both opencode and opencode desktop app:

ERROR 2026-04-03T23:55:58 +1019ms service=default e=Failed to initialize OpenTUI render library: Failed to open library "B:/~BUN/root/opentui-nsczjawe.dll": error code 126 rejection
ERROR 2026-04-03T23:55:58 +0ms service=default Error: Failed to initialize OpenTUI render library: Failed to open library "B:/~BUN/root/opentui-nsczjawe.dll": error code 126

Once put again both TMP/TEMP environment variables back to C:\ or any "normal" drive, opencode finally shown.

I've still another issue, as ollama local (not cloud) does not work at all with opencode/desktop app as it does not load any local LLMs correctly recognized and usable by Ollama/OpenWebUI, but I will open another issue for that.
