sorinj Fix Omaha reports 100% install progress between download and install. 
We now clear "InstallerProgress" under Google\\Update\\ClientState\\{AppID} before starting an install. So a client querying ICurrentState::installProgress never sees the value "100" from a previous execution.

The Chrome installer writes an install progress, but the Omaha CurrentState returns any previous value before the Chrome Installer can run. This results in showing values from a previous run of Chrome's installer, a brief flip from 50 to 100%, then to something between them.

Omaha

This is not an official Google product.

Omaha is the open-source version of Google Update, a program to install requested software and keep it up to date. The Google-branded version of Omaha is used to support software patching (both background updating, and on-demand update checks) for Google Chrome, Earth, and a variety of other Google products on Windows 7, 8, and 10.

We know that keeping software updated is both important and hard, and so by open-sourcing this project, our hope is that perhaps we can help others solve this problem. So, if you'd like to get involved, or even use Omaha to support your own software projects, then just follow the instructions in the Developer Setup Guide, and you'll be good to go!

There is also an unofficial tutorial. Please note that it was written by a third party so we cannot guarantee its availability, accuracy or safety.

You can’t perform that action at this time.
