Aucun symbole trouvé pour wmp.dll sous Windows 8.1

Question

Lorsque vous essayez de charger les symboles de débogage pour wmp.dll sous Windows 8.1, symchk indique qu'ils n'existent pas sur le serveur de symboles Microsoft (voir ci-dessous). J'ai également installé le Windows 8.1 x86 32-bit retail symbols, qui contient des symboles pour tous les autres fichiers WMP (wmplayer, wmpeffects, wmpshell etc.), mais pas pour wmp.dll.

J'ai également envoyé un e-mail à l'adresse bien connu windbgfb [at] microsoft [dot] com mais je n'ai reçu aucune réponse. Existe-t-il un autre moyen de demander à Microsoft de rendre ces symboles disponibles? Par ailleurs, ma version de wmp.dll est 12.0.9600.17415, ce qui, je suis sûr, est encore la version originale fournie avec Windows 8.1. Aucune mise à jour Windows contenant une version plus récente n'a été installée.

Answer 1

ok, j'ai une réponse. Mon soupçon était juste. Microsoft ne fournit pas la PDB pour WMP.dll en raison de problèmes de gestion des droits numériques. Vous devez résoudre votre problème sans PDB.
