function BOOL IsdotNetInstalled(szVer)
STRING szKey;
NUMBER nRes;
begin
szKey = "SOFTWARE\\Microsoft\\NET Framework Setup\\NDP\\v" + szVer;

nRes = RegDBKeyExist(szKey);

if(nRes < 0) then
//dotNet 4 is not installed
return 0;
else
return 1;
endif;

end; // end of function


you can also check the "Install" value under the same registry key (it needs to be equal to 1) using
RegDBGetKeyValueEx ( szKey, "Installed", nvType, svValue (here you will get 1 or 0 in case there is a key for dotnet), nvSize )

This code half work because to detect Framework 4 we must detect full or client version of version 4 like in this attachment
