Adobe Server Setup Tool --incemental issue with IIS (resolved)

Just sharing.

I set up an internal update server following the guide Use the Adobe Update Server Setup Tool (AUSST) for IIS on Windows 10.

The first day, I could install and update Adobe application through the apps tab.

I set up a nightly task to update the internal server (AdobeUpdateServerSetupTool.exe --root="..." --incremental)

The next day, I got a 404 error on the apps tab.

It appears that  the Adobe Update Server Tool deleted the "web.config" in the "ACC\services\ffc\icons" folder.

As a workaround, I put all the directives in web.config at the root level with "location" tags.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <staticContent>
            <mimeMap fileExtension=".dmg" mimeType="file/download" />
            <mimeMap fileExtension=".sig" mimeType="application/octet-stream" />
        </staticContent>
    </system.webServer>
    <location path="ACC/services/ffc/icons">
        <system.webServer>
            <staticContent>
                <mimeMap fileExtension="." mimeType="text/xml" />
            </staticContent>
        </system.webServer>
    </location>
    <location path="ACC/services/ffc/validation">
        <system.webServer>
            <staticContent>
                <mimeMap fileExtension="." mimeType="text/xml" />
            </staticContent>
        </system.webServer>
    </location>
</configuration>

Hope this will help!
