How to install BlogEngine in subfolder?

To install BlogEngine in a subfolder, you can use our one-click installer application, after it has been installed, you need to configure the parent application's web.config file. Wrap the existing <system.web> tag in the <location> tag as shown below.  If you still have a <system.webServer> tag in your parent application web.config file, wrap that in the same type of <location> tag too.  After these configurations have done, it will prevent the parent application settings from propagating down to the sub-applications.  To reiterate, these <location> tags should be added in the parent application web.config file -- not the sub-application's web.config file.

<location path="." inheritInChildApplications="false">
    <system.web>
             ..... existing content .....
    </system.web>
</location>

<location path="." inheritInChildApplications="false">
    <system.webServer>
             ..... existing content .....
    </system.webServer>
</location>
