Hi,

I have enabled on demand update through settings in Windows platform.

I am stuck with this REGDB_E_CLASSNOTREG issue.

An error occurred while checking for updates: Update check failed to start (error code 3: 0X80040154).

Regards,

Milan

If I run the updater.exe once, then issue is not coming. Any idea why?

What command line arguments do you run `updater.exe` with, if any?

updater.exe --install --app-id={8A69D345-D564-463c-AFF1-A69D9E530F96}

This works as intended.

Running the command line below makes the updater install itself (including its COM registration) and
then install the specified app. Therefore, the subsequent on-demand update calls done from the

browser succeed.

The browser can only do on-demand update checks if the updater is installed.

But to the end user we provide only the mini installer right? Do we need to provide the updater.exe also? In that case user has to run the mentioned command in prompt.

That is correct. The updater project builds a target named `UpdaterSetup.exe` - the metainstaller, which, when tagged or run with the appropriate arguments, forwards the arguments to `updater.exe`, which results in running the program with arguments similar to what you've passed by hand.

Side note for terminology: the mini installer is a program which is built by Chrome and installs Chrome. The metainstaller is an updater target, which installs the updater and the application specified by the tag or command line arguments.

The metainstaller contains `updater.exe`. You don't have to provide `updater.exe` to the user.

It is working fine end to end with UpdaterSetup.exe and omaha server.
