[英]Winform application not running on 64bit server
I have a winform application to read values from the registrykey..我有一个 winform 应用程序来从注册表项中读取值..
so i know i have to run as administrator in order to do so.所以我知道我必须以管理员身份运行才能这样做。
I have two servers of win 2003. one is 32 bit and the other is 64 bit.我有两台win 2003的服务器。一台是32位的,另一台是64位的。
When i run this application on my 32 bit i have no problem and it reads the values from the registry..当我在我的 32 位上运行此应用程序时,我没有问题,它会从注册表中读取值..
but when i run the application from my 64 bit server it cannot read from the registry.但是当我从我的 64 位服务器运行应用程序时,它无法从注册表中读取。
i get a我得到一个
system.nullreferenceexception
system.null 引用异常
as i cannot read the root of my reg key which returns null.因为我无法读取返回 null 的注册密钥的根。
i have put a manifest file also but with that too its not working..我也放了一个清单文件,但它也不起作用..
any help will be greatly appreciated... thanks..任何帮助将不胜感激...谢谢..
here is my manifest file:这是我的清单文件:

<!-- UAC Manifest Options
If you want to change the Windows User Account Control level replace the
requestedExecutionLevel node with one of the following.
<requestedExecutionLevel level="asInvoker" uiAccess="false" />
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
<requestedExecutionLevel level="highestAvailable" uiAccess="false" />
If you want to utilize File and Registry Virtualization for backward
compatibility then delete the requestedExecutionLevel node.

this is not the complete manifest as there are which i think wont be required to show here...这不是完整的清单,因为我认为这里不需要显示...
Have you verified that the key you're trying to read exists on the 64-bit system?您是否确认您尝试读取的密钥存在于 64 位系统上?
The path may be different for a 64-bit system: http://support.microsoft.com/kb/896459 64 位系统的路径可能不同: http://support.microsoft.com/kb/896459
If your registry key contains the text "WOW6432node", that's the 32-bit version.如果您的注册表项包含文本“WOW6432node”,那就是 32 位版本。 The 64-bit version will probably be the same except that part of the path won't be there.
64 位版本可能相同,只是路径的一部分不存在。
