From the guide http://dev.chromium.org/administrators/policy-list-3#ExtensionInstallForcelist it follows that this code in the batch file will add an extension to chrome

Reg Add "HKCU\Software\Policies\Google\Chrome\ExtensionInstallForcelist" /v "1" /t REG_SZ /d "gbchcmhmhahfdphkhkmpfmihenigjmpp;https://clients2.google.com/service/update2/crx" /f

But for some reason it does not work)

How can I install the extension in chrome, are there affiliate programs that sell instalia extensions, as they do?

    Starting from version 35 (35.0.1916.114 m), as is known (English), Google Chrome’s Windows browser has stopped supporting the installation of new and previously installed extensions that are not hosted by the Chrome WebStore.
