Documentation installation shows "Install failed: Validation Failed" when installing Android Build Support module

Package: Hub App

Cannot Reproduce

3.15.X

Thank you for reporting a bug to Unity. We have investigated the issue but were unable to reproduce it with the information provided. This can happen due to differences in environment, project setup, or steps taken. We will close this case for now. If you're able to share additional details such as different projects, steps, hardware/software configuration, or logs - please let us know, and we'll be happy to re-evaluate.

Steps to reproduce:

Open Unity Hub
Navigate to the Installs tab
Install (if not present) 6.4 Editor version (e.g. 6000.4.0b4 or 6000.4.0b3)
Click on Manage > Add modules
Select "Android Build Support"
Click Install
Observe the Downloads window

Actual results: Documentation installation shows "Install failed: Validation Failed"

Expected results: Installation shows no errors

Reproducible with versions: 3.15.4

Reproducible on: Windows 11
Not reproducible on: macOS 26.1 (M1)

Notes:

Could only reproduce with 6.4 Editors. The 6.0 and 6.3 installed Documentation with no errors, and 6.5 does not have Documentation available for Editor download
Tried reinstalling Hub and Editor versions, but the issue still persisted
