Originally assigned to: @dhiltgen on GitHub.

What is the issue?

Install from freshly downloaded installer. Ollama does not run server in background. Trying to run "Ollama app" - nothing happens, whether double clicked, or run from commandline. As server is not running, calls to e.g. "ollama run llama3.1 tell me why" reports server not running.
Expect old behaviour of being able to run a query after install.

Tried under user account and admin account, no difference.

Re-installed an old version from installer downloaded 22/04/2025, and behaviour as expected (will just ignore the update notiifications for now)

Relevant log output

Log only ever shows:

@PatParslow can you clarify which version works? Have you tried the latest version 0.10.0?

This might be a variation on #11447 with a C++ Redistributable compatibility problem.

When you installed or upgraded, did the MSVC C++ redistributable get installed as well? (UAC pop-up would have triggered prompting for permission)

Can you run the following and share what version is installed on your system?

Get-ItemProperty -path "Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\14.0\VC\Runtimes\X64"

Finally, try installing the latest version manually and see if the latest version of Ollama starts working again?

One other thing to try if the C++ redistributable doesn't resolve the problem... Install the latest version (currently 0.10.1) and if the latest version still doesn't resolve the problem, in a powershell terminal run:

$env:OLLAMA_DEBUG="1"
& "Ollama app.exe"

If no UI appears, then run explorer $env:LOCALAPPDATA\Ollama and see if anything more shows up in app.log

Not fixed. No MSVC issues here.

Followed troubleshooting steps in https://github.com/ollama/ollama/issues/11556#issuecomment-3141324884, entire contents of 'app.log' are below. Server log exists but is empty.

"C:\Users\USER\.ollama" exists, but is empty.

Sorry hadn't seen replies - not sure what my working old version was, but new 0.11.4 is working fine (to answer other part of query in case it is useful, not updating MSVC didn't help)

OK, apparently I just need to spend more time reading docs.

Started the server in one tab, then downloaded/installed/ran Open WebUI, uploaded a GGUF model via OWUI, and bob's your uncle.

Apologies for the noise.
