Hello @dfederm, I noticed that you’re changing an .swr file or any file under src/Package/MSBuild.VSSetup.. Please make sure to validate this change by an experimental VS insertion. This is accomplished by pushing to an exp/* branch, which requires write permissions to this repo.

This is fine and is what I did for other arches in #9547. I think we should consider changing the import to be $(MSBuildToolsPath32) but let's take this for now.
