Can't delete Registry.LocalMachine subkey

[Peri]

I can delete Registry.LocalMachine subkey using regedit. But not using
code:
RegistryKey eurotaxKey =
Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Firm\Application\Eurotax");
eurotaxKey.DeleteSubKey("pathDat");

I am administrator and regedit shows me that 'Administrators' have full
control
on Eurotax key. I've also given 'All users' full control to this key and
still I get System.UnauthorizedException with message "Cannot write to the
registry key".

There's no problem deleting from Registry.CurrentUser.

I assume this is from a C# app? Do you have registry permissions configured
correctly in CAS?

Your subkey is open for reading only, you have to open the subkey as "Writable", use the
overload of OpenSubKey that takes a boolean flag as second argument and set this one to
true.
