LabVIEW upgrade failure in NI Package Manager leaves repair-versus-reinstall decision unresolved

After a LabVIEW upgrade fails through NI Package Manager (NIPM), the immediate goal is to decide between repairing the current package in place or performing a clean uninstall and reinstall, without breaking other NI products that rely on shared run-time engines and drivers. The uncertainty is that NIPM can leave a product flagged as installed while files or dependencies are actually missing, and the Repair action may complete the current package without restoring the previous version.

Because LabVIEW supports side-by-side installations, a failed upgrade of one version does not necessarily destroy a working install, but a full removal may delete shared NI components that other products still require. The correct recovery path is version-sensitive and depends on whether the failure originated from a download, dependency conflict, or file-system issue, which the installation logs and Installed Software status can help classify.

What criteria should determine when NIPM Repair is sufficient versus when a full uninstall is necessary? How can the risk of removing shared NI components during a clean reinstall be assessed for other installed products? Which NIPM states and log entries confirm that a repair has fully restored the target LabVIEW version?
