網盤包括破解文件。
二、安裝
1、解壓RADStudio-1042-4203.iso文件
安裝外國人的東西盡量不要在中文目錄下，被整怕了，就習慣了不用中文路徑，得到兩個文件。
2、關閉Win10的病毒防護和其他殺毒軟件
1）左下角搜索按鈕，錄入def，找到“病毒和威脅防護”，點擊
2）右側找到“管理設置”，點擊
3）關閉病毒防護，安裝完再打開。
3、將破解文件解壓到安裝文件目錄
4、以administrator用戶運行安裝文件
1）勾選，同意協議，點擊Next
2）跳轉下一個界面后會生成“C:\ProgramData\Embarcadero”目錄
3）停留、停留、停留在下面這個界面
5、運行破解文件RADStudioKeyPatch.exe
1）點擊“Generate……”生成序列號，點擊“Patch……”生成破解文件
如果提示找不到 hosts文件，在cmd窗口中輸入for /f %P in ('dir %windir%\WinSxS\hosts /b /s') do copy %P %windir%\System32\drivers\etc & echo %P & Notepad %P
然后等幾秒種生成hosts文件后保存到C:\Windows\System32\drivers\etc目錄
patch時自己出現的問題，記錄一下
2）一路“Yes”“Ok”下去
3）完成后C:\ProgramData\Embarcadero這個樣子
6、回到安裝界面點擊“Back”
7、選擇“Use existing license”，點擊“Install”按鈕開始安裝
以上二步非常重要，成功后以下就正常安裝
8、等待、等待、等待
9、選擇安裝組件
10、等待、等待、等待、……
11、完成安裝
12、開始使用。
