手动删除ArcGis

今天想把本机的ArcGIS的版本从9.2更新到10.1。安装软件已经搞到手了，于是开始卸载ArcGIS 9.2 。

一开始是采用手动卸载，即删除文件目录和注册表等等。但在安装ArcGis10.1的时候总是说本机存在更低的9.2版本，不能安装。

采用他自带的版本呢卸载工具是一直报错，可能是有哪个地方没有卸载干净，但能找的地方都找了，于是想直接删除安装记录，使他检测不到以前的版本。在网上下载了一个叫 Windows Installer Clean Up 的工具来清除安装记录。

在安装记录里删除了9.2版本记录成功后，再次打开ArcGIS10.1的卸载工具，果然检测不到以前的版本了，小惊喜一把。可问题又来了，安装ArcGIS Desktop时，仍然报存在另外一个版本9.2，不能进行安装。

于是在万能的谷歌里面用英文搜了一出现的问题，搜到有位大神列出手动删除ArcGIS时需要清理的所有文件了注册表的地方。

按照一下列表进行一一清理，果然可以正常安装了。下面是列表：

原话：I advise a clean, manual uninstall of existing ArcGIS programs. Note: Paths may vary according to operating system. Also uninstall any third-party GIS programs that you may have installed.
Rename or delete following folders:

Rename: C:\Program Files (x86)\ArcGIS
Rename: C:\Program Files (x86)\Esri
Rename: C:\Program Files (x86)\Common Files\ArcGIS
Rename: C:\Program Files (x86)\Common Files\Esri
Rename: C:\Program Files\ArcGIS
Rename: C:\Program Files\Esri
Rename: C:\Program Files\Common Files\ArcGIS
Rename: C:\Program Files\Common Files\Esri
Rename: C:\Program Data\Esri
Rename: C:\Program Data\ArcGIS
Rename: C:\Program Data\FLEXnet
Rename: C:\Users\\AppData\Local\ESRI
Rename: C:\Users\\AppData\Local\ArcGIS
Rename: C:\Users\\AppData\Roaming\ESRI
Rename: C:\Users\\AppData\Roaming\ArcGIS
Rename: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\ArcGIS
Rename: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Esri

Go to regedit and rename/delete the following (if they exist):

Rename/Delete HKEY_LOCAL_MACHINE\SOFTWARE\ESRI
Rename/Delete HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ESRI
Rename/Delete HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Flex LM License Manager
Rename/Delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\
Rename/Delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ArcGIS Server
Rename/Delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\
Rename/Delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\FLEXnet Licensing Service
Rename/Delete HKEY_CLASSES_ROOT\Installer\Products\
Rename/Delete HKEY_CLASSES_ROOT\Installer\Assemblies\
Rename/Delete HKEY_CLASSES_ROOT\
Rename/Delete HKEY_CLASSES_ROOT\Installer\Assemblies\Global\

Next, Open Local Security Policy MMC

Go to Security Settings -> Local Policies -> Security Options
Locate "User Account Control: Run all administrators in Admin Approval" and change the setting from Enabled to Disabled
Uninstall: C:\Windows\assembly\Esri.* (This can be hundreds of files)
Uninstall: C:\Windows\assembly\ArcGIS.* (This can be hundreds of files)

如果以上办法还不行的，那就只能重装系统了。。。
