Why do you need this SetLastError(0)?

+        res = RegGetValueW(keyProfileDir,profile_subkey,profile_keyname,RRF_RT_ANY,
+                           NULL,buffer,&sizePath);  /* RegGetValue expects pcbData in bytes */
+        error = GetLastError();
+        RegCloseKey(keyProfileDir);

error isn't used after that.

+            /* else ("GetUserNameW failed\n"); */
+        }
+        /* else ("RegGetValueW failed - %d %d %d\n",res,error,sizePath); */
+    }
+    /* else ("RegOpenKeyExW failed\n"); */
     return FALSE;

What do these debug-comment lines mean?
