What is the issue?

platform: windows 10 21H2

Today when I want to upgrade Ollama, I decide to uninstall the old version first.

But after I uninstall the old version and install the new version, I found that all my models are gone, .ollama\models\manifests and .ollama\models\blobs are both empty. After a test, I found that the uninstaller will remove both directories, while the installer will create them.

I don't think this behavior is acceptable as it may cause data lose. It's better to have an option in uninstaller to keep models and keep it on by default.

I'm so sorry this happened. We'll revisit the uninstaller.

The latest uninstaller now offers the ability to choose if you want to retain or remove your models.
