Configure ActivePerl 5.12 on IIS 6/Windows 2003 Server

I have been running ActivePerl 5.6 on a Windows 2000 [server][1] for almost a decade. Recently I upgraded the server to Windows 2003. Then I deleted ActivePerl v 5.6 and installed the latest version of ActivePerl (v 5.12). The Perl code that used to run just fine now fails to execute properly. The problem I am having is that when the client browser displays a [web page][1] that contains a POST command to a Perl file on the server, the output that is presented to the client is displayed as raw HTML. I need someone who is familiar with ActiveState's ActivePerl and who can configure and debug the installation. Bid should be for completing the task of fixing our installation of ActivePerl. Communication will be accomplished either through Instant Messenger, Email, Phone, or GoToAssist
