Read WinGet Exit Codes in UniGetUI

Quick answer

A WinGet exit code describes the outcome of the underlying manager action, not necessarily a UniGetUI defect. Pair the code with command output, package identifier and installation scope.

Interpret failed WinGet commands and separate repository, installer and permission errors.

Before changing anything

Record the application version, Windows build, package-manager name, package identifier and exact error message. Back up important app data before making installations or removals. Verify commands against current documentation for your version.

Step-by-step checks

Copy the error code and full manager message.
Identify whether the failure occurred during search, download, installation or post-install detection.
Check source trust, administrator permissions and disk space for the specific step.
Re-run one action after addressing the evidence and compare installed version.

Limitations and safety

Exit-code descriptions can change between WinGet versions; verify against current Microsoft documentation.

How to confirm the fix

Repeat the operation on one package. Check the manager output, source identity and installed application version. If the error remains, capture the new error details rather than repeating broad resets.
