如果您之前已經安裝過個人版，請按照下列步驟清理後方可正常安裝企業版。
1. 啓動 D2007Tweaks.exe 擊 Advanced tweaks 選項卡，在 Remove license check 複選框上去掉已經打上的對勾，點擊 OK。
2. 卸載 Delphi 2007 for Win32。
3. 刪除 C:/Documents and Settings/All Users/Application Data/{AB3EC276-D261-4943-A921-1CC1C6799AED} （如果該目錄存在的話）。
4. 刪除 C:/Documents and Settings/All Users/Application Data/CodeGear 目錄及其子目錄。
5. 重新執行本光盤中的 Delphi 2007 for Win32 目錄下的 setup.exe 即可開始安裝。
6. 升級 delphi2007 時 setup.exe 在運行時報錯，內容是Attempting to get value of undefined variable HAS_SLIP。很明顯的，是找不到授權文件的數據。於是去 CodeGear 找了找，果然有解決的方法，現在記下解決的過程
1.下載 MSI Cleanup Utility，這個工具可以清除 msi 安裝時留下的註冊表數據
2.運行這個工具，找到 RAD Studio [5.0] 這個項，選中後點擊 Remove 按鈕，接下來可能會等比較長的時間，工具會清除 delphi2007 的註冊表安裝項。
3.找到 Documents and Setting 目錄，勾上“顯示所有文件和文件夾”，然後把 All Users 和 All Users.Widnows 下的 CodeGear 有關的目錄刪了（如果你只有 delphi 2007，就這麼刪，如果有 C++Builder2007，還要進目錄，只刪 delphi 的），把 {AB3EC276...... 刪除
4.現在就能正常安裝 delphi2007 update 1 了
原文如下:

Symptom: Attempting to uninstall, modify, repair, or upgrade Delphi 2007 RTM results in the error:
Line 12035: Attempting to get value of undefined variable HAS_SLIP
Cause: This problem occurs when the Delphi 2007 install cache directory has become corrupted or was manually removed.
Solution: The only known solution for this problem is to manually remove Delphi 2007 RTM from the system. The easiest way to accomplish this is to download the MSI Cleanup Utility from Microsoft's web site. Go to http://support.microsoft.com and search their Knowledge Base for article Q290301.
