Get a verbose log and see what's going on, if you haven't already. Are you sure that the cached MSI file is missing? For example, if there is a ResolveSource action that's not conditioned properly then Windows will want the original install source.
I have a vague memory of an issue in the \installer directory where the security settings made it inaccessible, but I can't find any docs on that.

Subject: [WiX-users] Uninstall issues Hello WiX Users! I've been running into an issue more often that I care to see. When uninstalling a package via ARP, a dialog pops up stating the installer cannot be found, and prompts the user to locate the MSI on a network share / CD drive. This also shows up when running a major upgrade. What seems to be happening is the stripped MSI is not being stored in the C:\WINDOWS\Installer directory. This does seem to be a rare issue, but one that is starting to concern me. I mostly see this on XP systems, I don't recall any non-XP boxes honestly, but can't be 100% sure on that. Most (99%) installs/uninstalls work without issue. Any thoughts what could be causing this issue?
