Mein VPN lässt sich nicht installieren da es keine 32 Bit Anwendung ist

Hi to everybody who can help me.
This is my question: Actually the version of Windows is Windows XP professional  and if I start to install AVG secure VPN there is the answer on the screen:
avg_secure_vpn _setup.exe ist keine zulässige Win32-Anwendung ! 
How can I install AVG secure VPN without this upcomming message ?
Waiting hopefull for your answer

Thank you for writing back to us in English, Fritz.

We regret to inform you that the AVG Secure VPN is not compatible with Windows XP Professional.
In this case, we'd recommend you to upgrade your operating system & try the installation of AVG Secure VPN.
Thank you for understanding in advance!
