Good day everyone!
I just want to ask, how do you create a registry key in this location
Software\Microsoft\Windows\CurrentVersion\Uninstall

I tried the code below (I stole this somewhere :( , credit who ever coded it) and it is obviously adding a subkey in Software Key

C#

RegistryKey key = Registry.LocalMachine.OpenSubKey("Software",true);

key.CreateSubKey("AppName");
key = key.OpenSubKey("AppName", true);


key.CreateSubKey("AppVersion");
key = key.OpenSubKey("AppVersion", true);

key.SetValue("yourkey", "yourvalue");

So, I tried it by changing the

C#

RegistryKey key = Registry.LocalMachine.OpenSubKey("Software",true);

to

C#

RegistryKey key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall");

and it is now giving me an exception which is
'System.UnauthorizedAccessException' occurred in mscorlib.dll

Thank you for the help everyone!

You need to run with administrator privilege to add items to the HKLM hive.

Yes right now, the request priveldge is "requireAdminitrator" so I am running the code with admin rights.

Solution 1

Entries in Software\Microsoft\Windows\CurrentVersion\Uninstall are typically created by Windows Installer. Hence create an intsaller for your program, and do not try to write there from your application proper!

Thanks for the help! Well, there is a situation that the application that I am trying to check in the registry can run even when the key of that application is deleted so I want regenerate that key in the registry.
