winapi - How to use RegDeleteTree to delete KEY_WOW64_64KEY key? -

-

i have tested regdeletetree() in 32bit program. delete key_wow64_32key key. there function regopenkeyex() specify key_wow64_32key or key_wow64_64key ?

i have tired code:

hkey key = null; if (regopenkeyex(hkey_local_machine, _t("software\\asd"), 0, key_read | key_wow64_64key, &key) == error_success) {     long d = regdeletetree(key, null);      if (d != error_success)     {         cout << "error" << d;     }     else     {         cout << "success";     } }

the output success key still exits in registry. i'm running on windows 7 vs 2013 , compiled win32 program not x64.

use regopenkeyex key_wow64_64key open 64 bit view of key. call regdeletetree passing returned key.

regarding update. ask read access when opening key. documentation regdeletetree states:

the key must have been opened following access rights: delete, key_enumerate_sub_keys, , key_query_value.

the fact call succeeds anyway makes me think process subject virtualization. need have manifest process forces uac elevation. use requireadministrator option in manifest.
