問題一：
Installing .NET Framework Runtime 4.0: D:\安裝包\CAD\cad2012(x64)\Map3D2012(x64)\3rdParty\NET\4\wcu\dotNetFramework\dotNetFx40_Full_x86_x64.exe
Install .NET Framework Runtime 4.0 Failed Installation aborted, Result=1603
原因是計算機已經安裝了.NET 4.0（如系統自帶或安裝其他軟件時自動安裝），安裝CAD時重復安裝就會出錯，解決辦法為：
打開安裝文件夾中的“Setup.ini”；
在DOTNET BEGIN到DOTNET END之間每個.NET版本安裝完后加上“IGNORE_FAILURE=YES”，表示安裝失敗時忽略，並保存：
