[otrs] Installing phpmyadmin on windows install?

If I want to install phpmyadmin on the windows install of otrs 2.4.7. . .where do I put the folder? I put it under cgi-bin and it gives Internal server error. If I put it under the main htdocs, then it just displays the text of the php files. . .probably just an apache understanding issue, but thought I would ask. Thanks.
