.NET Runtime for Xeno — when Windows asks
Missing framework prompts are a runtime issue. xeno-executor.rest does not want you to skip them and grab a patched EXE.
Install the framework
- Read the error: Desktop Runtime vs just “.NET”. Prefer Desktop Runtime x64.
- Download from Microsoft. Install. Reboot if told.
- Launch Xeno from the excluded folder as Administrator.
- Attach only after Roblox is in a place.
Still prompting
Wrong runtime SKU or x86 vs x64. Install Desktop x64, then retry the same official folder.
Questions on this host
SDK or runtime?
Runtime. You are not compiling Xeno.
Can I ignore it?
The window will keep dying. Fix the framework.
Does this host ship .NET?
No. Microsoft does. This site only documents the order.
