我已经知道如何检查用户是否在系统上安装了4.0版,即通过检查以下内容:

 bSuccess := RegQueryDWordValue(HKLM, 'Software\Microsoft\NET Framework Setup\NDP\v4    \Client', 'Install', iInstalled);
 if (1 = iInstalled) AND (True = bSuccess) then bVer4x0Client := True;
 bSuccess := RegQueryDWordValue(HKLM, 'Software\Microsoft\NET Framework Setup\NDP\v4        \Full', 'Install', iInstalled);
 if (1 = iInstalled) AND (True = bSuccess) then bVer4x0Full := True;

 if (True = bVer4x0Full) …
