Unable to launch RDM (InvalidOperationException...

Hi,

I try to use Remote Desktop Manager (free) 5.7.3.0 on Windows XP Pro SP3, and when I launch RDM :


InvalidOperationException - Le fichier exécutable du compilateur c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\csc.exe est introuvable.

Do you know why ?
