Sorry for my newbie question and my English. DWMHook only works on x32 systems for me. The line "AppInit_DLLs"="C:\AeroGlass\\DWMGlass.dll" from file LoadGlass__AppInit_DLLs.reg has been fixed for the next "AppInit_DLLs"="C:\\Portable\\MyDWM\\DWMGlass.dll" but it still does not work. Anyone have any ideas how to fix it? System files have been patched by UltraUX Theme Patcher. Thanks!
