ArcGIS 10的色带重复问题

ArcGIS 10版本中，在图层属性对话框中对图层进行渲染，选择渲染色系时，弹出的色带有重复。以下是针对该问题的处理建议。

1. A. Close all ArcGIS applications and rename the ESRI folder under C:\Users\YourUserProfile\AppData (need to show the hidden folders)\Roaming\ESRI. Rename the "ESRI" folder to "ESRI_Old".

B. Reset Registry Keys

a. Start Menu --> Run --> type "regedit" (without quotation marks). 
b. Expand HKEY_CURRENT_USER folder.
c. Expand Software folder within HKEY_CURRENT_USER.
d. rename the esri folder to ESRI_Old.
e. File > Exit.

Above procedure will force the software to create new template files and associated registry counterparts. After performing both of the above steps, restart ArcMap. If the issue you are experiencing is an artifact of corrupt template files, this procedure will resolve the issue. 

2. Please try uninstalling any third-party tool or extension we are using with ArcGIS and check to see if the issue still persists.

3. If nothing appears now, it would be appropriate to test logging into the machine as a different Windows user to see if the error still occurs. If it does, our next step is to "Repair" the installation of ArcGIS Desktop via Add/Remove programs.

4. Clean installation 
-- Uninstall ArcGIS and the ArcGIS Help. Remove any ArcGIS programs from the Add/Remove Program List
-- Uninstall all Python programs from the list
-- Go to the following directory: C:\Users\UserName\AppData\Roaming and delete the ESRI folder
-- Go to Start > Run and type regedit and press the Enter Key
-- Delete the ESRI Folder in HKEY_CURRENT_USER > Software
-- Delete the ESRI Folder in HKEY_LOCAL_MACHINE > Software
-- Delete the ESRI Folder in C:\Program Files\Common Files
-- Delete the ArcGIS Folder in C:\Program Files
-- If the ArcGIS program still exists in the Add Remove Program list, download the Windows Installer Cleanup Utility (Google that) and it will clean up that list.
-- Reinstall ArcGIS: Choose "Complete" installation. (Python will install automatically)
