Autocad 2008 installation error in VISTA 64bit

here is exactley what i did, get orca from here:
http://www.technipages.com/download-orca-msi-editor.html

and then follow these steps:

1. Download and install Orca from Microsoft.
2. Copy the installation files to your hard drive or a network folder.
3. Backup the files ACA.msi and Setup.ini
4. Edit the ACA.msi with Orca and delete the action found in the table
"InstallExecuteSequence" that is called "CheckFor64BitOS" Delete the same
line under table "CustomAction"
5. Save and close the ACA.msi
6. Edit the Setup.ini with Notepad. Delete the line under
"#==================== Platform Requirement" that is labeled
"PLATFORM=NO_WOW_64_PROCESS"
7. Double-click the Setup.exe and you should be able to install without any
problems.

MAKE SURE YOU COPY ALL THE FILES FORM YOUR CD OR DVD TO YOUR HARD DRIVE...I HAD TWO CDS AND I COPIED BOTH TO A NEW FOLDER WITHOUT CHANGING NAMES, WHEN PROMPTED TO "FILE ALREADY EXIST" I CLICKED YES TO ALL. IT WILL NOT ERASE IT WILL ADD THE FILES TOGETHER. AND AFTER MODIFYING THE FILES USE THE ICON CALLED "ACAD" NOT THE SETUP ONE. actually i did not bother modifying the steup file i just did the "aca" one and used it and it worked perfectly. when registering the program at the end it will freeze on you... left it for a few minutes shut down the program, restarted and it worked. hope that helped

在电脑上安装ＡutoCAD 2008，进行到Flash项时出现了以下提示：“Error 1904.Module C:\WINDOWS\system32\Macromed\Flash9.ocx failed to register. HRESULT -2147220473. Contact your support personnel.”应当如何解决呢？



Flash9.ocx注册失败
方法一：
重新注册以下DLL文件，你在桌面上点“开始”、“运行”：
regsvr32 Shdocvw.dll
regsvr32 Shell32.dll
regsvr32 Oleaut32.dll
regsvr32 Actxprxy.dll
regsvr32 Mshtml.dll
regsvr32 Urlmon.dll
重启系统后如果无效就看方法二：
重新下载一个完整版Macromedia Flash V8.0 简体中文版
