I have installed ActivePerl 5.10 in WindowsXp. When i try to run the code am still getting the below mentioned error

Then, your Perl is not build to support threads. Get a Perl that was built to support threads.

Personally, I doubt that you are running the Perl you think you are running. You can verify what version of Perl you are running by starting

perl -V
[download]

This will inform you about the Perl version and the directories it uses.

I ran the command perl -V in my system and got the following output. Can you suggest me whether it conveys any useful data for my issue

What you have downloaded probably isn't ActivePerl.

ActiveState no longer offers 5.10 for download, except if you paid for Business Edition and Enterprise Edition

If you paid for Business Edition and Enterprise Edition, you also paid for support, so contact contact ActiveState for support
