Lookup Installed Version in the Clients Registry

If an installer is abandoned or an app is modified by an external source
the version in the updater prefs may be out of sync with the installed
version. To prevent these values from getting out of sync lookup the
product version in the `Clients` registry, and, if its a valid version,
override the version in the updater prefs.

This fix is not necessary on macOS because `LookupVersion` is already
implemented on macOS to lookup the version in the app's registered
plist.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
