Sorry if have violated ur polocies. string[] tArray = (string[]) Registry.GetValue(keyName, "TestArray", new string[] {"Default if TestArray does not exist."}); for(int i=0; iwithin that key, and have even replaced the text within the OpenSubKey call to be an exact copy of the key name as retrieved from

  • Antonym for Nourish Reverse a hexadecimal number in bash Build me a brick wall!
  • India just demonetized all Rs 500 & 1000 notes.
  • Your 32 bit process, by default, reads from the 32 bit view of the registry.

I could fix my issue using the flags mentioned by Miral. I got a look at Registry Redirection and Reflection but could not see a solution. if I rename the 64bit key out of the way, leaving the 32bit key, the code fails to return the 64bit key.. try to change like this: Dim regkey As RegistryKey regkey = Registry.LocalMachine.OpenSubKey("SOFTWARE\Valve\Steam", False) If regkey IsNot Nothing Then Try Dim steampath As String = CStr(regkey.GetValue("InstallPath")) Catch ex As Exception MsgBox("Cannot read

Thats why, the following code is WRONG: Dim blabla as RegistryKey = Registry.LocalMachine.OpenSubKey("HKEY_LOCAL_MACHINE\SOFTWARE\.....", False) because you already opened the localmachine registrykey when you said Registry.LocalMachine.OpenSubKey. Reading steampath works perfectly, its reading from the "SandboxieVersion" from "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Sandboxie" that doesnt work the only difference i can see is the fact its reading from a different part of the And also, make sure you read a STRING value from registry... Check This Out Why this error?

I figured out that the information about app was installed correctly on HKLM\SOFTWARE\Wow6432Node\MyCompany\MyApp\ registry key. I have no idea why it can't read it. I execute the setup file on x64 machine.

For example, in Visual Basic the string "HKEY_CURRENT_USER\MyTestKey" accesses key/value pairs for the subkey "MyTestKey" in the HKEY_CURRENT_USER root.

I've verified the key location and value does exist. I have checked and the registry entry is in place, and I ran the program as Administrator. so you dont need to type that into your path, like this regkey = Registry.LocalMachine.OpenSubKey("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Sandboxie", False) The above thing will result in HKEY_LOCAL_MACHINE\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Sandboxie which obviously does not exist. Yes its a C++ code but after seeing this API(RegOpenKeyEx), I thought I have a similar kind of problem and so I have posted my query.

www.byteshift.com .NET 4.0 has updated mscorlib to include the "Microsoft.Win32.RegistryView" enum which includesRegistry.Default, Registry.Registry32, Registry.Registry64. The installer creates registry keys under HKLM\SOFTWARE\COMPANY\APP and copy files to Program Files\Company\App. I stumbled upon this as I was debugging my code and am curious why my added fake_entry doesn't work. http://outwardsound.com/cannot-read/cannot-read-registry-4story.html The content you requested has been removed.

When I try to run my .Net 32 bit app, surprise to see it can read the keys on registry and find correctly the directories in Program Files. This is how we are calling the API:   hr = RegOpenKeyEx ( hKeyBase, newPath, 0, KEY_ENUMERATE_SUB_KEYS | KEY_QUERY_VALUE, hKey);   Can you tell me how you have solved your problem To test is, open the parent key `SOFTWARE\Trebuchet\ServerSetup` and get a list the sub keys. –Joel Coehoorn Jun 14 at 4:52 add a comment| 1 Answer 1 active oldest votes up share|improve this answer answered Jun 15 '12 at 16:50 Graham Wager 1,65111223 add a comment| up vote 2 down vote Here is how you can open up the 64-bit hive.

RegistrySubkey are the sub-keys of the above keys, meaning sub-levels of the reggistry keys. I think the problem is with the access permissions we are using.
