I'm trying to run sample Perl script on Windows 7 and I configured IIS 7 to allow ActivePerl to run but I'm getting this error:

 HTTP Error 502.2 - Bad Gateway The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are "Hello World. ". Module CgiModule Notification ExecuteRequestHandler Handler Perl Script (PL) Error Code 0x00000000 Requested URL http://localhost:80/hello.pl Physical Path C:\inetpub\wwwroot\hello.pl Logon Method Anonymous Logon User Anonymous

and here is my Perl script:

#!/usr/bin/perl print "Hello World.\n";

The first output returned from any CGI program should be the headers.

Try

#!/usr/bin/perl print "Content-type: text/plain\n\n"; print "Hello World.\n";

A related situation would be when you are getting this error while installing WordPress.

A really simple solution that helped me out of my frustrations is to simply allow permissions to the folder where your website is installed. I got this problem when I could not install WordPress project. After going round and round the web, that is what it came down to: folder permissions!

How is this a "related situation"? Wordpress is not using Perl at all, and the accepted answer contains a completely different solution than yours
Related because of this "HTTP Error 502.2 - Bad Gateway. The specified CGI application misbehaved..." I guess that is how I ended up in this thread. There aren't many solutions I could get that pointed me to that little fact
Please add all clarification to your answer by editing it
This is more of an edit to my answer above: I had set up a self-hosting service using Windows Server 2022. I then setup Handler Mappings and FastCGI Settings for PHP. When I installed WordPress, it loaded well with my websites. However, when I applied themes to any of the websites I was getting this error. It took me quite a while to find a solution, which was simply applying read-write permissions for the logged in users (WordPress users) to the website folders.
