问题 Can anyone tell me why I can't access the registry key of "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData" ? if I query the GetSubKeysNames of "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer" it only returns one value being "Secure" ----> Where are all the other subkeys? Thanks. 回答1: High odds that you are running your program on the 64-bit version of Windows and it is forced to run in 32-bit mode. The registry redirector will make you

问题 In .Net we can retreive the paths to 'special folders', like Documents/Desktop etc. Today I tried to find a way to get the path to the 'Downloads' folder, but it's not special enough it seems. I know I can just do 'C:\Users\Username\Downloads', but that seems an ugly solution. So how can I retreive the path using .Net? 回答1: The problem of your first answer is it would give you WRONG result if the default Downloads Dir has been changed to [Download1]!

问题 Description One driver left a mess in the registry (even when I uninstalled it from the system). If I check the security setting it will not display anything in “Group or user names”. And when I check the owner it shows only “Unable to display current owner.”. When I want to delete the registry keys I have to: Take the ownership. Add group. Delete the key. The problem is that each registry has several sub keys and I have to repeat the process on each key. Inherit permission option will not

问题 I can't seem to delete a registry key when I uninstall. Note that this isn't a repeat of this question, as I don't think that I have the same problem.
