DeleteSubKey UnauthorizedAccessException

Question

I'm trying to write a quick app to modify some registry keys. When I'm browsing via RegEdit, I can modify and delete the keys with no problems.

But when I try to use RegistryKey.DeleteSubKey() it throws an UnauthorizedAccessException .

Is there any way to gain the privileges to do this? Also, why would there be a problem if my user account obviously has access to make the changes?

Edit:

Here's some code

RegistryKey reg;

try
{
    reg = Registry.CurrentUser.OpenSubKey(BaseKey);
    reg.DeleteSubKey("{" + Item.Guid.ToString() + "}");
}
catch
{
    return false;
}

Answer 1

Try this instead, open it initially as read/write instead of read-only:

RegistryKey reg;

try
{
    reg = Registry.CurrentUser.OpenSubKey(BaseKey, true); //<--over here!
    reg.DeleteSubKey("{" + Item.Guid.ToString() + "}");
}
catch
{
    return false;
}
