Re: Detect .NET presence

Here's what we ended up doing:

   public static boolean isDotNET2Available()
   {
      RegistryKey r =3D new RegistryKey(RootKey.HKLM, "SOFTWARE\\Microsoft\=
\.NETFramework\\policy\\v2.0");

      if (log.isDebug())
         log.debug(r + " exists: " + r.exists());

      if (r.exists() && r.hasValue("50727"))
      {
         RegistryValue value =3D r.getValue("50727");

         if (log.isDebug())
            log.debug("Registry value: " + value);

         return value !=3D null && "50727-50727".equals(value.getStringValu=
e());
      }

      return false;
   }

The jRegistryKey library comes from here: http://sourceforge.net/projects/j=
registrykey/.

There's always calling a native method that tries to create an instance of =
a
.NET AppDomain in the same process....
