for debugging d3d9 applications enabling directx 9 debug runtime essential.

(the june 2010 sdk must installed first.)

for 64-bit applications can enabled in directx control panel (64-bit) checking use debug version of direct3d 9.

problem: resets retail when control panel closed, , doesn't anything.

(the 32-bit equivalent works.)

kjell andersson found answer:

the problem originates windows 7 update locked down hklm\software\microsoft\direct3d registry key user named trustedinstaller. made administrator not having rights update settings in registry key - not allowing switch debug version of direct3d 9.

to fix problem have follow procedure:

  2. select permissions... context menu on key.
  3. press advanced button.
  4. go owner tab , select administrator owner. apply changes , close advanced settings.
  5. back in premissions dialog select administrators group , check full control. apply changes , close dialog.

you able start directx control panel directx sdk june 2010 , switch debug runtime.
